Despite a posted speed limit of 30 mph, a Cobb County man admitted to driving up to 80 mph before causing a fatal crash that killed his 19-year-old passenger, according to police.

On Nov. 15 around 2:20 p.m., Isaiah Williams was driving on Marble Hill Road at Kenmill Drive, near Marietta, when he lost control of his green 1996 Infiniti I30, left the roadway and hit a tree, Cobb police said.

Christopher Martin, the front seat passenger, was critically injured in the crash. The 2015 Marietta High School graduate died from his injuries the following day at WellStar Kennestone Hospital.

Williams was also injured in the crash, but his injuries were not serious, according to police. He was arrested and charged with first-degree vehicular homicide, reckless driving, failure to maintain lane and possession of less than an ounce of marijuana, his warrant states.

Investigators believe it was excessive speed that caused the fatal crash, Williams’ warrant states.

“Mr. Williams stated that he knowingly operated the Infiniti at speeds ranging between 70 and 80 miles per hour,” the warrant states. “Roadway and vehicle evidence at the collision scene were also indicative of speeds that exceeded the 30 miles per hour speed limit.”

Police also found suspected marijuana in the center console of the car, and a hand-rolled cigarette, the warrant states.

Williams was arrested Wednesday and booked into the Cobb jail. Later that night, he was released on $50,000 bond, booking records showed.
