Dry-Labbing Exposed: El Paso DPS Crime Lab Fakes Results of Blood Alcohol Tests

In 2015, criminal defense attorneys, Brent Mayr and Tommy Carter, working with the assistance of forensic toxicologist, Amanda Culbertson, were called upon to review a case of an individual arrested and charged with DWI in El Paso, Texas. A police officer had stopped and arrested the person and, acting pursuant to a No Refusal Program, obtained a search warrant and had the person’s blood drawn. The vials of blood were delivered to the Texas Department of Public Safety’s El Paso Regional Crime Lab where the blood was to be tested by analysts to determine the blood alcohol concentration. After several months, the lab released an official lab report stating that the blood alcohol concentration was over the legal limit. While most individuals would think they had no choice but to plead guilty, this individual insisted that he was not intoxicated and asked Mayr, Carter, and Culbertson to take a closer look. Mayr and Carter obtained an order from a judge requiring the crime lab to produce all records related to the testing of their client’s blood. The records revealed what appears to be one of the most egregious acts that a laboratory could commit: dry-labbing. “Dry-labbing” is a term used where a lab reports that they performed a test producing a result when, in fact, no test was ever performed or the data was manipulated in a way contrary to what naturally occurs. Stated differently, it is where a lab reports “fake results.” How Blood is Tested to Determine BAC To understand the gravity of and provide clarity to this issue, one needs to be familiar with some of...

Hurricane Harvey’s Effect on the Criminal Justice System

When Hurricane Harvey hit the Southeast Texas region in August 2017, it destroyed and flooded thousands of homes and businesses. With such impact, then, it should come as no surprise that it also greatly affected both the federal and state criminal justice systems throughout the region. This picture is worth the colloquial “thousand words.” This is the Harris County Criminal Justice Center a day after the rain stopped coming down. The massive flooding caused the Buffalo Bayou, located two blocks from the building, to come out of its banks and flood the northern edge of downtown Houston. Although the building was improved after Tropical Storm Allison in 2001 to prevent water damage, including the installation of flood doors (which can be seen directly behind the front, glass doors), water was still able to permeate the building’s basement causing severe damage. This lead to sewage backing up and coming out of toilets and water fountains on the upper floors. There was also damage to upper floors from cooling pipes bursting from unregulated pressure. The building contained 22 criminal district felony courts, 16 criminal county misdemeanor courts, the District Attorney’s Office, the Public Defender’s Office, the Office of Pretrial Services, and Court Administration. Now it is empty. All occupants were required to move out as the building will have to undergo massive repairs that are expected to take 9 months (but we all expect to take about 18). As a result, courts, prosecutors, and staff have had to relocate. Criminal District Courts are now sharing courtrooms with Civil District Courts in the Civil Courthouse which did not sustain any damage. The...

Feds Crack Down Again on Health Care Fraud

The need for having an experienced, knowledgeable federal criminal defense attorney has never been greater today than it has been in several years. Today, Attorney General Jeff Sessions and Department of Health and Human Services (HHS) Secretary Tom Price, M.D., announced the largest ever health care fraud enforcement action by the Medicare Fraud Strike Force, involving 412 charged defendants across 41 federal districts, including 115 doctors, nurses and other licensed medical professionals, for their alleged participation in health care fraud schemes involving approximately $1.3 billion in false billings. Of those charged, over 120 defendants, including doctors, were charged for their roles in prescribing and distributing opioids and other dangerous narcotics. Thirty state Medicaid Fraud Control Units also participated in today’s arrests. In addition, HHS has initiated suspension actions against 295 providers, including doctors, nurses and pharmacists. The charges — like most prosecuted by the Department of Justice — aggressively target schemes billing Medicare, Medicaid, and TRICARE (a health insurance program for members and veterans of the armed forces and their families) for medically unnecessary prescription drugs and compounded medications that often were never even purchased and/or distributed to beneficiaries. The charges also involve individuals allegedly contributing to the opioid epidemic, with a particular focus on medical professionals involved in the unlawful distribution of opioids and other prescription narcotics, a particular focus for the Department. According to the CDC, approximately 91 Americans die every day of an opioid related overdose.   The Gov’t Has a Medicare Fraud Strike Force, Who Do You Have To Fight Against Them?

Health Care Fraud Criminal Defense

Federal authorities recently announced that roughly 300 people in more than half the states have been charged in the largest crackdown to date on health care fraud.  Those arrested accounted for more than $900 million in false billings to Medicare and Medicaid.  Among those arrested were 60 licensed medical professionals, including 30 doctors.  The billings were for treatments or services deemed medically unnecessary — or for services that were never provided at all, including home care, medical equipment, and phony prescriptions. Offenses Charged in Health Care Fraud Schemes Individuals in these cases are typically charged with various health care fraud-related crimes. These include conspiracy to commit health care fraud, violations of the anti-kickback statutes, money laundering and aggravated identity theft.  The charges are based on a variety of alleged fraud schemes involving various medical treatments and services, including home health care, psychotherapy, physical and occupational therapy, durable medical equipment (DME) and prescription drugs.  In this specific case, more than 60 of the defendants arrested were charged with fraud related to the Medicare prescription drug benefit program known as Part D, the fastest-growing component of the Medicare program overall. Typical Schemes Allegedly Used Defendants in these cases are typically alleged to have participated in schemes to submit claims to Medicare and Medicaid for treatments that were medically unnecessary and often never provided.  In many cases, patient recruiters, Medicare beneficiaries and other co-conspirators are allegedly paid cash kickbacks in return for supplying beneficiary information to providers.  The providers will then, in turn, allegedly submit fraudulent bills to Medicare for services that are considered medically unnecessary or never performed. The Gov’t Has a Medicare...

Brent Mayr Convinces Grand Jury to Toss Out Vehicular Manslaughter Charges; Client Now Going After GM

It has been a long, traumatic road for Zachary Stevens and his family. With the help of Brent Mayr, however, not only is he on the road to freedom, he also stands to hold the real party responsible for his tragic story accountable. On November 15, 2011, around 4:30 in the afternoon, Zachary Stevens left his home in a neighborhood right off of FM 1485, a couple of miles east of US-59 in New Caney. Severe weather and rain showers had just moved through the area and the roadways were still very wet. Zach was traveling westbound on the two lane highway with a number of cars ahead of him following each other fairly close. All of a sudden, Zach recalled one of the vehicles applying their brakes. The rest of it was a blur to him. According to witnesses, he swerved onto the shoulder to avoid colliding with the slower vehicles, passing them on the shoulder. Once past the vehicles, Zach was able to maneuver his car back into the westbound lane of travel. The wet roads, however, proved to be too treacherous. The tires of his vehicle lost their traction and Zach’s car began to hydroplane. It would “yaw” from the westbound lane into the oncoming traffic in the eastbound lane. Traveling in the opposite direction in a Nissan Frontier pickup truck was Mariano Landaverde. He was not wearing his seat belt. He tried to take evasive action but was unable to avoid the nearly head-on collision. Although his vehicle was equipped with one, his airbag failed to deploy. Between that and his failure to wear a...
