|E-Newsletter Introduction and Invitation
TCAS, LLC is sending this first edition of our newsletter to all our past and present clients with the hope that it is of value to your professional endeavors.
Welcome to our new series of short, educational summaries of forensic toxicology matters taken from actual TCAS cases over the past 25 years. Each case summary is factual, however, identifying case information has been removed unless revealed through jury verdict reports. Although interesting to read, the purpose of these case summaries is to show you how the application of toxicological principles can be used in forensic matters. On occasion, we will also be releasing summaries on new toxicological studies and regulations.
In the event you have an interesting case you would like to discuss, please feel free to call or email myself or Jen for a prompt, confidential teleconference appointment.
Postmortem Alcohol Formation in a Severe Burn Victim
CASE STUDY: TCAS Plaintiff matter (Duval, FL, 2011-CA-001772; Theodore Leopold, Esq, Palm Beach Gardens)
Female plaintiff was involved in a collision in Florida during July, 2008, while riding as a passenger in a Ford F-150 truck driven by her boyfriend. Although the woman suffered only minor injuries during the collision, the truck's fuel system was alleged to be defective when the gas tank was ripped open as the truck ran over a stop sign post cutting through the plastic safety shield covering the plastic fuel tank. The ensuing gasoline spill caused a massive fire with flames shooting more than 20 feet into the air. The fire breached the passenger compartment of the truck killing the boyfriend and causing catastrophic injuries to the Plaintiff including the loss of both of her legs and portions of her hands and forearm with severe burns over much of her body. The Defendant claimed that the Plaintiff and her boyfriend were both intoxicated as, prior to the accident, they had both been at a bar.
Postmortem Alcohol Formation
Upon review of the matter, Dr. Sawyer noted that the quantity of alcoholic beverage consumed at the bar was discrepant with respect to the postmortem blood alcohol concentration (BAC) of 0.11% noted for the driver and was also discrepant with the postmortem urine and bile alcohol concentrations when applying generally accepted conversion equations. Such data immediately raised a "red flag."
Review of the autopsy report and photos of the driver revealed that approximately 95% of his body was burned so severely that striated muscle and bones were visibly evident. Although not well known to most professionals, it is generally accepted and documented within the toxicological literature that severely burned postmortem bodies more often than not produce endogenous alcohol. This postmortem alcohol formation stems from microflora deposits upon the open tissues with rapid alcoholic fermentation occurring. This phenomenon has been studied and published in articles by the Federal Aviation Administration (FAA) following the autopsies of hundreds of plane crash victims known not to have consumed alcohol, USS Iowa turret gunnery disaster victims in 1989 and in many other severe burn cases.
Following multiple depositions, motions to preclude his testimony and a hearing before the judge, Dr. Sawyer was permitted to present the evidence regarding postmortem alcohol formation. After a lengthy three week trial, the jury returned a finding that the fuel system was defective and, therefore, partially responsible for the catastrophic injuries to the Plaintiff, resulting in a 4.3 million dollar verdict against Ford Motor Corporation.

| Munchausen Syndrome or Toxic Exposure?
CASE STUDY: TCAS Defense matter
A female Nebraska Plaintiff was stocking vending machines as part of her job duties when she slipped and fell on a floor which was in the process of being refinished with a chemical wax stripper. The plaintiff reported that she sustained chemical burns over a large portion of her body from the stripping product even after spending 20 minutes rinsing off in the shower immediately following her fall. She also alleged that the chemical burns caused her to develop a condition known as methicillin-resistant Staphylococcus aureus (MRSA) due to damage to her immune system. In addition, she also reported a swollen eye which she believed to be related to this event. Plaintiff subsequently brought a lawsuit against the floor refinishing company.
Munchausen Syndrome revealed
A careful review of the medical records revealed various inconsistencies within the Plaintiff's story. Additionally, Plaintiff demonstrated an extensive medical history of skin rashes, blistering, cellulitis and frequent MRSA, which pre-dated her alleged exposure. Statements from Plaintiff's co-workers revealed that she had been seen intentionally injuring herself by repeatedly sticking her fingernail in her eye. Dr. Sawyer and an independent medical examiner opined that there was no permanent impairment of the Plaintiff's skin following her exposure, nor was there any reason to believe that her immune system was permanently damaged or compromised by exposure to the chemical stripping product. In fact, Munchausen syndrome - a mental illness in which a person acts as if he or she has a physical or mental disorder when, in truth, the symptoms are self-inflicted - was considered to be the cause. The presentation was highly consistent with Plaintiff's extensive history of skin rashes, self-induced dermatological conditions, hospitalizations and the reported self-mutilation to her eye.
Were chemicals the cause?
Dr. Sawyer was able to provide conclusive evidence that the diluted chemical ingredients were insufficient to have caused her reported injuries. Furthermore, even if the chemical components of the stripping product had been undiluted, they would have caused skin symptoms to occur within one half hour or less. However, Plaintiff's first indication of any dermatological issues as documented in the medical records occurred a full 22 days later - far outside the required time-frame to be linked to the chemical stripper. In addition, the stripping product had been diluted with water by a factor of five further reducing any dermatological impact. The case settled for a very minimal amount as Dr. Sawyer was able to demonstrate that the Plaintiff's claim was unfounded.
