Cobb County investigators believe an 18-year-old man was driving 83 mph when he caused a fatal crash Saturday afternoon in Mableton.

John Kevin Rangel-Gonzalez was driving a 2005 white Chevrolet Tahoe south on Mableton Parkway about 5 p.m. when he struck the driver’s side of a Ford Mustang that was attempting to turn left into the highway, according to Cobb police.

“The Ford was projected approximately 150 feet from the point of impact,” Rangel-Gonzalez’s warrant states. “The Chevrolet continued approximately 200 feet while rolling after the collision.”

The driver of the Ford, 42-year-old Tricia Tinch of Mableton, died in the crash. After being arrested, Rangel-Gonzalez was treated for injuries at Wellstar Cobb Hospital and later booked into the Cobb jail, records show.

A passenger in the Tahoe was taken to Grady Memorial Hospital for treatment of injuries that were not life-threatening.

Investigators said Rangel-Gonzalez’s speedometer was stuck at 83 mph. The posted speed limit in the area is 45 mph. He did not have a driver’s license, according to police.

Rangel-Gonzalez, who lives less than a mile from the crash site, was charged with first-degree vehicular homicide, reckless driving, speeding and driving without a license, according to police. He was released Sunday afternoon after posting $20,000 bond, jail records show.

The crash remains under investigation. Anyone with additional information for investigators is asked to call 770-499-3987.
