According to Oxygen (February 19, 2025), an autopsy conducted by the Tarrant County Medical Examiner revealed injuries that suggested his body had been moved after death, shifting the case from an accident to a homicide investigation.

The postmortem report, conducted on October 28, 2001, detailed multiple fractures, a severe abdominal laceration, and scratches across his body. Investigators pointed to lividity, or blood pooling after death, found on his shoulders and front torso, contradicting the initial assumption that he died at the scene of impact.

Gregory Biggs’ case will be revisited in season 2 episode 5 of Prosecuting Evil with Kelly Siegler, airing February 22, 2025, at 8 pm ET/PT on Oxygen True Crime.

On October 26, 2001, Chante Mallard, a 25-year-old nurse’s aide, struck Gregory Biggs, a homeless man, with her vehicle while under the influence of alcohol, marijuana, and ecstasy.

The impact sent Biggs over the hood and into the windshield, where he became lodged, suffering severe injuries as per an article on PEOPLE, dated March 12, 2018. Instead of calling emergency services, Mallard drove home, parked her car in the garage, and left Biggs trapped.

According to trial testimony, Mallard repeatedly checked on Biggs but never sought medical assistance, even as he remained alive for hours.

Dr. Nizam Peerwani, the Tarrant County Medical Examiner, testified that while his injuries were critical, timely medical intervention could have saved his life as per CBS News, June 26, 2003. The doctor added:

“He was obviously in severe, excruciating pain."

Gregory Biggs died in Mallard’s garage, bleeding to death over approximately two hours. After his death, Mallard sought help from two acquaintances, who moved Biggs’ body to a nearby park and attempted to destroy evidence by setting fire to her car, as reported by PEOPLE.

The case remained unsolved for months until Mallard, believing she had escaped consequences, discussed the incident at a party. A guest reported her to the police, leading to her arrest.

According to court records, Mallard has no reported infractions in the past 15 years and is eligible for parole in 2027.
