Suspects has been sentenced to 75 years in prison for aggravated robbery after stabbing a Lyft driver multiple times
FRISCO, Texas — Antwain Karmen Williams, 20, has been sentenced to 75 years in prison for aggravated robbery after stabbing a Lyft driver multiple times during a December 16, 2024, carjacking.
According to the Collin County District Attorney’s Office, the Lyft driver suffered severe injuries, including a slit throat and a badly cut hand, but survived.
Investigators discovered Snapchat messages showing Williams planned to steal a vehicle to kidnap a 13-year-old child. Police later arrested Williams after he fled in the stolen vehicle and crashed.
Williams pleaded guilty to aggravated robbery, and a Collin County jury sentenced him to 75 years in prison.
Snapchat messages recovered from Williams’ phone revealed he intended to steal a car that night to kidnap the child. Law enforcement tracked Williams as he fled in the stolen vehicle, crashed into another car, and was taken into custody by Texas Department of Public Safety Trooper Justin Diaz.
Following his arrest, Williams offered conflicting accounts, initially blaming a fictional person before claiming the Lyft driver had locked him in the car and that he attacked only to escape.
However, prosecutors presented damning digital evidence, including a Snapchat photo of Williams smirking while holding the stolen keys with the caption “we mobile baby,” alongside messages stating “I’m boutta get a car.”
During the sentencing trial before Judge Jim Pruitt, jurors heard evidence regarding the robbery, the pending child exploitation case, and a pattern of additional misconduct. Detective Walker Martin testified about phone records detailing Williams’ illegal relationship with the child victim.Â
