Expert Witness Corner: A Fire Investigator?s Qualifications

Whether an attorney instructs a fire investigator to carry out work or is facing one across the courtroom it is essential that the lawyer satisfy himself or herself that the expert is properly qualified.

It is a young science and has evolved greatly of the last several years. Due to advances in the science of fire investigation certifying bodies and the courts are paying close attention to who qualifies and how. Investigations are conducted for various reasons ranging from those conducted by public fire departments to identify origin and cause, and whether or not any criminal activity was involved; to those privately financed by insurance companies and individuals to attempt to assign blame and recover loss. This article will discuss the range of education, training, experience, and certifications involved.

Education and Certifications

Formal education various greatly. The National Fire Protection Association (NFPA) 1033 “Standard for Professional Qualifications for Fire Investigator” is a standard for minimum requirements. The NFPA 1033 dictates in general that at a minimum, the investigator must be at least 18 years old and possess a high school diploma or equivalent. In general most will have various educations beyond this minimum. Formal education often varies from an associate’s degree in fire science to bachelors, masters, or doctoral degrees in engineering or other technical sciences.

There are numerous certifications available to demonstrate the minimum levels of competence. The two most recognized associations in the United States that certify are the National Association of Fire Investigators (NAFI) and the International Association of Arson Investigators (IAAI). NAFI offers three certifications that act as entry-level certification and documentation of education and experience. These certifications can be obtained upon completing various amounts on-scene training and completing varying amounts of training, often obtainable by attending various directed conferences. Upon meeting the applicant requirements, all of these certifications require passing a comprehensive written examination.

NAFI offers three different certifications; these are the Certified Fire and Explosion Investigator (CFEI), the Certified Fire Investigation Instructor (CFII), and the Certified Vehicle Fire Investigator (CVFI).

The IAAI offers two certifications which are the Fire Investigation Technician (IAAI-FIT) and the Certified Fire Investigator (IAAI-CFI). The IAAI-FIT is this association’s entry-level certification and requires a minimum of 18 months of general experience and a minimum of 44 hours of tested training. There is then a comprehensive examination. The IAAI-CFI has a much more rigorous application process that must be completed and approved before an applicant may sit for the certification examination. The requirements of the IAAI-CFI include a minimum of 4 years of full time experience, certain testimony experience or training requirements, education and training, and various other requirements that are set up on a point system. The applicant must complete the application meeting all the points requirements and include verification of every item listed.

Other agency specific certifications exist, but the most recognized may be the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) Certified Fire Investigator (ATF-CFI). This in-house certification applies scientific and engineering technology training in a 2-year training program. The ATF special agent must undergo a minimum of 6 weeks of classroom training and gain hands on experience of at least 100 fire scenes under the direct mentorship of an ATF-CFI.

Public Sector Fire Investigation

The public sector F.I is usually one employed by the government, such as fire department, state fire marshal’s office, etc. The range of education, training, experience, and certifications varies greatly in this category. Fire department investigators are often fire fighters that have moved into the fire investigations unit. They often receive in house training that is passed down from colleagues. Their background often includes an associate’s degree in fire science related to fire fighting with some training. Often, fire department fire investigators will work in this position for many years however the department’s budget is often limited when it comes to sending employees to outside training and conferences which is a requirement for independently recognized F.I certifications. The lack of funding for outside training can lead to not only a lack of certifications, but also a lack of awareness of the advances in the science. Fire departments will often send at least their lead investigators to the Fire Academy and to locally sponsored conferences.

Often, fire marshal F.I’s have transferred from a different position. The F.M’s office often has a less restrictive budget with respect to providing training. F.M.I’s often have or are on path to acquire various certifications.

The next level comes from federal agencies such as the Alcohol, Tobacco, and Firearms (ATF). ATF investigators go through a rigorous two-year training program to obtain the ATF’s Certified Fire Investigator Certification (ATF-CFI).

Private Sector Fire Investigation.

Private sector investigators are those that do not conduct work for government agencies, but are hired by insurance companies, attorneys, or other individuals to determine the origin and cause of fires. They range from ex-public sector fire investigators to engineers, chemists, and other technically degreed individuals whose careers have led them into fire investigation. They normally have more flexible budgets for attending conferences, seminars, and other forms of continuing education, which tends to become a job requirement in order to comply with the recertification requirements of the various certifications they may hold.

Attorneys should therefore always bear in mind when they are trying to find an expert witness that the person they eventually use must have impeccable credentials and qualifications that cannot be challenged by their opponent.

Responsibilities of Structural Engineers as Expert Witness

Expert civil engineers in the construction field have great deal of responsibilities in their job. They directly accountable for the management and planning when it comes to construction dams, reservoirs, buildings, railroads, bridges, and highways. Not only do they assist in designing but they also participate in estimating costs, planning, scheduling, obtaining materials, choosing equipment used, and controlling costs.

However, there is a huge difference between an expert consultant and an expert witness. A consultant may be any person whom a client relies on to be especially well-informed and reliable for assisting with the technical sections of a problem. The recognition and work of the expert consultant may or may not be revealed to the other parties in the legal action unless and until it is finally decided that he or she will be an expert witness. This particular decision is made by the legal team based on the opinion hold by the consultants, the legitimacy of that opinion, the strength of his or her expected testimony, and, as the bottom line, the value of the testimony to the accomplishment of the case.

The work of an expert witness engineers is not much different from examining and reporting on any building project. The legal procedures for the examination are similar to that of any other professional work, requiring precision, knowledge and good reasoning capability. Once the engineer is faced up to the rules of the legal profession, he or she must be aware of the additional rules of forensic activities. This does not modify the general procedures for engineering work, but even makes it imperative to know the conduct and performance of an experienced witness.

It is a must that an expert witness engineers must possess work experience, advanced technical degrees, and certifications in many disciplines and sub disciplines as well including Materials Science and Engineering, Chemical Engineering, Mechanical Engineering, Metallurgical Engineering, Welding, and Corrosion. Among other qualifications, expert witnesses must also specialize in:

Identify defects or evidence of maltreatment

Finding out physical, chemical or mechanical of materials

Helping in subrogation claims

Developing protocols for precision evidence analysis

Determining requirement compliance

Giving detailed and impressive deposition and trial testimony

High-end instrumentation and qualified proficiency

Overall, it is believed that the truthful expert witness is the most valuable and necessary professional in the resolution of claims.

Expert Witness Corner: Inflicted Childhood Neurotrauma (Shaken Baby Syndrome)

Introduction:

Previous evidence has suggested that the shaking of a relatively heavy head about the neck causes such inertial forces within the brain tissue that shearing takes place with rupture of meningeal vessels and diffuse axonal injury, resulting in subdural haemorrhage and neurological damage. The retinal haemorrhages are generally thought to be due to the same shearing mechanisms at work within the vitreoretinal interface. There is a correlation between intra-ocular bleeding, anterior optic nerve haemorrhage and subdural haematomas. When looking at the relative positions of subhyloid haemorrhages at post mortem, it was found that the frequency of position of these haemorrhages coincided with the areas of maximal vitreoretinal adhesion, that is the ora serrata and the optic disc.

Post mortem findings of vitreous traction at the apex of retinal folds and the edge of dome shaped haemorrhages and retinoschisis gives some supporting evidence that vitreous forces may cause this shearing damage. There is no adequate model to test this experimentally, so this remains hypothesis, not established fact. In the situation of isolated intraocular haemorrhage with or without accompanying subdural haemorrhage there continues to be disagreement regarding the possibility of an accidental injury such as a short fall in the domestic setting being responsible for the clinical findings in the absence of other evidence to support non-accidental injury.

The Royal College of Ophthalmologists Working Party concluded in terms of the force required to cause retinal haemorrhages : “..no absolute values can be given for the angular acceleration forces required to produce injury but there is good evidence that they must be considerable..”

In 2003 ‘Brain haemorrhage in babies may not indicate violent abuse’ appeared as a headline in the BMJ following a not proven verdict in the case of a child minder accused of murder at the High Court in Edinburgh. During this case research was presented which purportedly cast doubt that the injuries could only have been due to violent shaking.

Research:

Geddes and colleagues, in a series of papers presented their findings that the most common pathological finding was of brain swelling and hypoxic ischaemic encephalopathy with a significant number of cases having focal axonal damage in the lower brainstem rather than diffuse axonal injury as previously thought. They hypothesized that damage to the brainstem, by hyperextension–flexion (shaking) injury at the craniocervical junction may cause focal damage, resulting in apnoea, and a cascade leading to hypoxic ischaemic encephalopathy, brain swelling, raised intracranial pressure and death. (This has been referred to as the ‘unified hypothesis’.) They further suggested that hypoxia-related leakage of blood from veins both inside the dura and in the subdural space was the source of the subdural haemorrhage rather than traumatic rupture of bridging veins and that in the immature brain hypoxia alone is sufficient to activate the pathophysiological cascade which culminates in altered vascular permeability and extravasation of blood, so that the subdural and retinal haemorrhages were a secondary phenomenon and not due to shearing forces. This led to the conclusion that “..it may not be necessary to shake an infant very violently to produce stretch injury to the neuroaxis…”

These comments related to those difficult cases in which there was little or no external evidence of injury but there were retinal and thin film subdural haemorrhages.

Other researchers have similarly reported the finding of hypoxic ischaemic damage rather than diffuse axonal injury but have not drawn the same conclusions regarding the forces involved.

However in terms of ocular examination there is no description of the retinal haemorrhages, they were either present or absent and they do not mention whether the optic nerves were examined. In the first paper they comment that “…a discussion of the aetiology of retinal haemorrhages…is beyond the scope of this paper. Later in their third paper they discuss the possible cause of retinal haemorrhages;

“ ..retinal haemorrhages can be explained by rises in intracranial pressure and central venous pressure, with and without hypoxia; they are also seen in a proportion of normal infants at birth, as well as in premature babies . In the setting of inflicted infant head injury, it has never been proved that retinal bleeding is directly caused by shaking; rather, it is widely assumed that it results from the shearing forces of the injury, which simultaneously cause retinal and subdural bleeding and diffuse brain damage. However…most infant victims…show very little ..traumatic pathology in the brain, it is appropriate to re-evaluate this assumption….”

Geddes’ pathological findings add little new evidence to the knowledge of retinal haemorrhages in shaken baby syndrome. In evaluating the latter Professor Luthert, an ophthalmic pathologist reviewing the various theories of causation (shearing forces vs other rheological mechanisms), timing and nature of injury concluded:

“….I consider it premature to consider that the eyes are in some way an independent arbiter of mechanism or severity of injury…”

The Geddes publications drew much attention particularly from those involved in child protection because of there conclusions. Punt published a lengthy rebuttal the main thrust of the which suggested intrinsic flaws within the research and a lack of evidence to support the unified hypothesis.

Geddes recently replied to Punt seeking to clarify their hypothesis explaining that whilst some had severe corticospinal pathology a few had strikingly little axonal damage:

“…In other words, in terms of numbers of axons injured, such an injury was trivial and totally survivable. What was not trivial was the child’s response to that injury…we do not know the minimum force needed to stretch the neuroaxis…..” .

Yet again they extrapolate this time from the fact that only a few nerve fibres may need to be damaged means only minimal force may be required to cause this small amount of damage but that the response was catastrophic, and that the damage to a small number of axons would be in itself survivable. This sounds plausible and intuitive, but just because only a few nerve fibres are damaged (and in some cases no obvious axonal damage in this area was found) does not prove that it does not require much force to cause this damage. It would seem that it is not that in terms of the number of axons damaged that determines that it is a trivial injury and survivable but it is the location of that damage.

The main scientific finding of Geddes in the first two papers was that in cases of retinal haemorrhages with thin film subdurals and in the absence of other injuries that the pathological finding is more commonly that of hypoxic ischaemic encephalopathy rather than diffuse axonal injury. This seems to have been lost in the subsequent arguments over the forces required to produce these findings.

Conclusion:

The cause of retinal haemorrhages, including the biomechanics of vitreo-retinal traction, raised intracranial pressure, changes in vascular permeability all remain unproven hypothesis as does the suggested mechanism of haemorrhage from Geddes. We are trying to make informed decisions on the basis of necessarily incomplete observational data, using inadequate mathematical, anthropomorphic and animal models which do not reflect the true nature of the normal infant nor the forces involved in shaking. The minimum forces required to cause such haemorrhage are not known and given that previous assumptions have been based on calculations relating to the generation of diffuse axonal injury, the use of the finding of retinal haemorrhages in isolation as a surrogate measure for the forces involved becomes dubious.

Regardless of the recent debate the observational evidence to date remains that children with non accidental injury may have no visible retinal haemorrhages, whilst non accidental injury and birth are the only circumstances in which multiple retinal haemorrhages in differing layers of the retina have been accurately documented.

This small albeit difficult group should not divert us from a willingness to evaluate the literature critically, participate in reasoned debate and in further research and certainly not detract from the main message… DON’T SHAKE THE BABY!

As a postscript, I would urge any lawyer who has a client who is facing accusations of child abuse, particularly those involving SBS, to instruct an experienced expert witness who can deliver an unbiased, objective report and, where appropriate, oral testimony. As can be seen from this article, the issues involved are extremely complex and are not without opposing views.

New York Using Whistleblower Law as Part of Systemwide Effort To Pursue Tax Evasion Aggressively, According to Young Law Group


Philadelphia, PA (PRWEB) April 30, 2014

New York State is actively pursuing businesses that have engaged in tax evasion and wealthy taxpayers who are hiding income offshore. The New York False Claims Act permits individuals to share in the proceeds from these enforcement efforts if they bring forth evidence of tax fraud that results in successful collection efforts from a taxpayer. Unlike many states which do not provide for rewards in tax cases, the law allows accountants, financial professionals and employees of businesses, as well as others who wish to do the right thing when they discover wrongdoing, an avenue to report their information to the government and seek recovery on behalf of their fellow taxpayers.

“Recent enforcement actions by New York demonstrate that the state is actively pursuing collection efforts against tax evaders and would be interested in evidence about others,” according to Eric Young, Esq., Managing Partner of Young Law Group, P.C. “Individuals who have evidence of deliberate evasion or underpayment of taxes, including sales tax, should consult a whistleblower attorney about the procedure for reporting to the government and the potential for a reward based on their information.”

Prior to 2010, New York State did not pay for tax tips. In 2010, New York removed the exemption for cases of tax fraud in the False Claims Act, permitting whistleblowers with evidence of businesses avoiding payment of income taxes or the state sale tax to file a lawsuit to share in the state’s recovery. New York is beginning to see results from the change of the law.

Attorney General Eric T. Schneiderman and New York settled a qui tam whistleblower lawsuit in March brought against Lantheus Medical Imaging Inc. by a tax service provider for alleged failure to pay New York State and City taxes in Anonymous v. Anonymous, case number 102892/2012, Supreme Court of the State of New York, County of New York. Lantheus agreed to pay $ 6.2 million in the settlement for engaging in business in New York without paying applicable taxes.*

New York is also pursuing a tax fraud lawsuit initially brought by a whistleblower against Sprint-Nextel Corp that claims Sprint-Nextel failed to collect state and local taxes on flat-rate access charges for wireless calling plans. It estimates that Sprint has allegedly failed to pay $ 130 million in taxes, resulting in a case for damages of nearly $ 400 million.** The lawsuit is People of the State of New York et al. v. Sprint Nextel Corp. et al., case number 103917-2011, in the Supreme Court of the State of New York, County of New York.

New York’s use of the False Claims Act appears to be part of a systemwide effort to pursue cases of tax fraud. The Department of Taxation and Finance collected 5 percent more in evaded taxes in the 2013-14 fiscal year than it did the prior year.*** The increase of approximately $ 200 million brought the total achieved through enforcement programs for the year to $ 3.9 billion. Additionally, the Department of Financial Services, led by Superintendent Benjamin M. Lawsky, is also conducting an investigation into whether Credit Suisse aided taxpayers in tax evasion. A dual purpose of the inquiry, according to the New York Times, is to recover tax revenue lost by the State of New York. ****

“The real victims of tax fraud are the taxpayers who diligently and honestly pay their taxes every year,” said James J. McEldrew, III, Esq., Of Counsel at Young Law Group, P.C. “Individuals who come forward and tip the government to fraud are performing a public service. The False Claims Act recognizes the valuable contribution they make to society.”

Expert Witness Corner: SIM Card Data Retrieval – The Essentials

The Importance Of SIM Cards:

There are more mobile telephones in the UK then there are people – this pervasive technology impacts on almost all areas of industry and life. Unsurprisingly, mobile communications have enabled old crime to be effected in new ways and mobile telephones are increasingly forming a part of criminal prosecutions, where linkages between individuals or evidence of being at the scene of the crime is provided by an analysis of the digital evidence available within the mobile phones.

At the heart of every mobile telephone is the Subscriber Identity Module (SIM), a small fingernail sized chip, responsible for service with a telecom network provider.

Digital Evidence From SIM Cards:

Despite limited memory capacity, the SIM contains a wealth of information that, when considered in context, can greatly aid lawyers in their case preparations:

• Stored telephone numbers/contacts.

• Listings of ‘Last Dialled Numbers’.

• Text messages received, sent, drafted or deleted.

• General location information from last use.

• References to overseas network providers that have been used.

Common Questions:

Q: Could the SIM card have been cloned?

A: SIM cards produced after June 2002 employ the COMPv2 algorithm which provides a number of technical and security safeguards to prevent unauthorised modification. Despite media reports, the cloning of modern SIM cards is an extremely rare practice.

Q: Can my PIN code be cracked?

A: SIM card information can be locked using a four digit ‘Personal Identification Number’. RIPA contains provisions to force disclosure of passwords, however, it is usually easier to request a ‘Phone Unlock Key’ (PUK), enabling PIN settings to over- ridden, from the Data Protection Officer (DPO) at the relevant network provider.

Q: PAYG SIMs are untraceable!

A: With ‘Pay As You Go’ (PAYG) there is no formal contract with a network provider (e.g. Orange) to enable a customer look-up, however, ‘Call Data Records’ (CDRs) are still available from the network provider, providing information as to patterns of communication, calls to/from, time/dates etc. By mapping this information to known acquaintances of the defendant, considering the evidence in the context of other material (such as messages recovered from the telephone handset) and undertaking Cell Site Analyses (CSAs)3 it is possible to prove/disprove ownership of a handset.

Q: Does the SIM reveal who I’ve been in touch with?

A: Even without the disclosure of Call Data Records (CDRs) from the network provider, the SIM provides a plethora of useful information relating to contacts in the form of ‘Last Numbers Dialled’ (LND) and sections of the ‘Contacts Directory’. Numbers that haven’t been saved may still show up in the LND.

Q: Can a telephone handset be uniquely identified?

A: Mobile phone handsets are assigned unique 15-digit numbers, known as the International Mobile Equipment Identifier (IMEI), which is passed to the network provider before communication services can be utilised. This serial number allows specific handsets that have been stolen or blacklisted to be blocked from a network irrespective of what SIM card is inserted. Defences suggesting that a given handset has been ‘found’ and is not owned by the suspect are unlikely to hold water if Call Data Records (CDRs) show a pattern of usage that indicate the owners identity.

Q: What about sending anonymous texts?

A: They are not really that anonymous… If they are being sent via an internet service, there is typically a log retained by the site provider as to the computer IP address that sent the specific message – this can ultimately be tied by to an Internet Service Provider (ISP), and in turn a specific subscriber. If anonymous texts have been sent from a mobile telephone – typically a PAYG handset/SIM – the uniquely assigned International Mobile Subscriber Identifier (IMSI) code embedded in the SIM can be used in concert with CDRs to provide compelling evidence as to the sender identity.

Q: Can deleted text messages & numbers be recovered?

A: Data content (especially multimedia formats) is primarily stored on the handset or on a removable memory stick. The general rule of thumb is that any data that has been deleted can be recovered, however, if it has been over-written it does make the process more complex and the chances of success reduce with every over-write.

Q: Is possession of multiple SIM cards indicative of wrongdoing?

A: Not at all – many individuals are discovering that they can benefit greatly from the free text and talk allowances granted on mobile phone contracts by having two or more SIMs (typically with different network providers). Adapters are available to connect multiple SIMs to a handset simultaneously.

Did you know?

The SIM card will often contain a reference to the last network base station that it communicated with before being disconnected from the telecoms network.

If the SIM card has been used overseas, it is possible to retrieve a reference code from the card that will indicate which national/regional network provider was used.

Language preferences can be stored on SIM cards – useful intelligence for investigators which can open up new avenues of enquiry.
