Chante Jawan Mallard was born on June 22, 1976, in Fort Worth, Texas. She was raised in a regular household in this city. Growing up, Chante was described as a bright and active child. She attended local schools and was involved in various activities. As she got older, she pursued a career in healthcare, becoming a nursing assistant.

During her teenage years, Chante faced some challenges. She struggled with personal and family issues, which affected her life. Despite these difficulties, she worked hard and maintained her job in nursing. Chante's life took many turns, and she faced various ups and downs.

Chante lived in Fort Worth throughout her early adult life. She became known to her friends and family. As a nursing assistant, she was expected to help others. 

On the night of October 26, 2001, Chante Mallard was driving her Chevrolet Cavalier in Fort Worth, Texas, while under the influence of a combination of alcohol, ecstasy, and marijuana. While operating her vehicle, she struck Gregory Glenn Biggs, a 37-year-old homeless man who was walking along the road. The impact was so severe that Biggs was lodged in her windshield, his body partially penetrating the glass. Critically injured and bleeding, Biggs remained alive and conscious.

Rather than call for emergency services or attempt to help, Mallard drove home with Biggs still embedded in the windshield. Upon arrival at her residence, she parked the car in her garage—leaving the injured man trapped and slowly dying. Despite being a trained nursing assistant, Mallard failed to render aid. According to reports, she checked on him occasionally over the next two to three days, during which time Biggs died from his untreated injuries. Expert witnesses later testified that had he received prompt medical attention, his life could have been saved.

After his death, Mallard enlisted the help of Clete Denel Jackson and his cousin Herbert Tyrone Cleveland to dispose of the body. The trio removed Biggs from the windshield, drove him to a park, and dumped the body. In an effort to destroy evidence, they set fire to part of the car. Their involvement would later lead to additional charges.

Mallard might have gone unnoticed, had she not bragged about the incident at a party months later. Reportedly laughing, she told an acquaintance, “I hit this white man.” This revelation led to a tip that eventually resulted in her arrest. A grand jury indicted her, and her trial began on June 23, 2003.

During the trial, Tarrant County Medical Examiner Nizam Peerwani and other emergency responders testified that Biggs would have survived had Mallard simply taken him to the hospital. Fort Worth Fire Department Captain Jim Sowder testified that every member of his department could have saved Biggs’s life had they been called.

Mallard was convicted of murder and sentenced to 50 years in prison. She was also convicted of tampering with evidence, receiving an additional 10-year sentence, though it was ordered to run concurrently. Under Texas law, she will be eligible for parole in 2027.

In the aftermath, Gregory Biggs's son, Brandon, filed a wrongful death lawsuit, which was settled out of court. Brandon publicly forgave Mallard and the others involved in his father's death. In a symbolic act of support, inmates from across the country raised $10,000 to fund a college scholarship for him. At the time, Brandon was a 20-year-old pastoral ministry student in Texas.

Co-conspirator Clete Jackson has since been in and out of prison on drug and firearms charges. The exact nature of Jackson’s and Cleveland’s relationship to Mallard remains unclear, though some reports suggest a romantic link between Mallard and Jackson.
