The man charged in a grisly South by Southwest hit-and-run that left two people dead is now facing a second first-degree murder charge. According to CBS Austin, the suspect, 23-year-old Tyrone Thompson, was slapped with additional charges following the April 16 death of William Dunham, 34, who succumbed to injuries sustained during the March 12 incident. The first victim, Cody Shelton, 26, died at the crash scene.

Thompson's litany of charges reads like a rap sheet from a hardcore crime drama: murder, driving while intoxicated, resisting arrest, obstruction, unlawful carrying of a weapon, accident involving death, accident involving serious injury, and aggravated assault with a deadly weapon. He's set to make a court appearance in June. Details leading up to the tragic event indicate that the incident unfolded rapidly. KVUE reports that Austin Police Department officers were patrolling downtown on the early morning of March 12, when they spotted a vehicle connected to drug activities and violent crimes.

The driver, identified as Thompson, made an erratic getaway, running red lights and ultimately hitting the two pedestrians at East Seventh and Red River streets around 1 a.m., the documents state. The chaos didn't end there. About an hour after the initial collision, Thompson was involved in another crash on Wolfe Lane in Del Valle, for which Travis and Bastrop County deputies responded, finding Thompson noncompliant and reeking of alcohol.

In a remarkable attempt to absolve himself, Thompson claimed to the deputies that he hadn't been behind the wheel and that his mother had just dropped him off. However, upon contacting his mother, the Travis County deputy found no truth in his claim, effectively tying Thompson to the scene of the crime. The aftermath has left the Austin community shaken and the victims' families grappling with a senseless loss.
