A 26-year-old man was seriously injured early Tuesday when his car hit a parked truck, causing it to hit another parked vehicle, Cobb County police said.

“Investigators believe excessive speed and alcohol may be contributing factors in this collision,” Cobb police Officer Sarah O’Hara said in a news release.

Shortly after midnight, a 2003 Toyota Camry driven by Shakir Williams of Atlanta was traveling south on Crossing Creek Point near Austell when it went into oncoming traffic before briefly leaving the road, O’Hara said.

Williams drove back onto the road, then hit a 2012 Ford F-350 pickup truck that was parked in front of a residence, according to O’Hara.

“Because of the impact from the Toyota, the Ford was projected forward into a red 1990 GMC Safari Van, which had been parked in front of the Ford,” O’Hara said. “Both the Ford and the GMC were unoccupied when they were struck.”

Williams was taken to Grady Memorial Hospital with life-threatening injuries, O’Hara said. A male passenger was also taken to Grady, but his injuries are not considered life threatening.

Anyone with information is asked to contact police at 770-499-3987.
