Irving police public information officer John Argumaniz provided more details on the early morning wreck that killed Brown and led to a second-degree felony charge against Brent at a press conference outside police headquarters on Saturday.
Argumaniz explained that after failing field sobriety tests, Brent was transferred to a hospital, where he had blood drawn, which is standard procedure in cases like this. When police learned Brown had died as a result of injuries sustained in the accident, Brent's driving while intoxicated charge was altered to intoxication manslaughter.
Brent will be kept in custody until a magistrate hearing scheduled for Sunday morning. His bond will be set at that time.
Argumaniz said evidence at the scene indicates Brent's car was going well over the posted 45-mph speed limit when it struck a curb, flipped at least once and slid approximately 900 feet before coming to rest on its roof in the middle of a service road. Responding officers extinguished a fire coming from the car, though the vehicle was not engulfed.
Brent suffered minor scrapes but was otherwise unharmed.
Argumaniz asked anyone who may have witnessed the accident to contact Irving police.
