A Colbert County man was killed Tuesday when the motorcycle he was riding slammed into the back of a pickup truck on U.S. 72, authorities said.

Phillip Barry Manley, of 1535 Red Rock Road, Tuscumbia, was 58.

State troopers said the crash site was three miles west of Tuscumbia, between the Locust Shore community and Pride Landing, and occurred just before 2 p.m.

Colbert County Coroner Carlton Utley pronounced Manley dead at the scene about 30 minutes later.

Utley said Manley died from multiple blunt force trauma to the head.

The driver of the pickup, Harley Kent, was not seriously injured, troopers said.

Both vehicles were eastbound on U.S. 72, based on witness accounts.

Troopers said it appears Manley, who was driving a 2004 Yamaha Road Star motorcycle, ran into the back of the 1994 Chevrolet 1500 pickup as Kent was turning into a driveway.

Emergency crews at the scene said the impact was so severe that it broke the rear housing on a riding lawn mower that was in the bed of Kent's pickup. The truck was heavily damaged.

The collision also broke the motorcycle's front fork.

Will T. McCrory and his wife, Clarice, live a few yards from where the accident occurred.

"I heard something, but I didn't know what it was at the time," Clarice McCrory said. "I looked out and saw a lot of cars stopping in front of the house."

"I went out, looked up the road and I could tell it was bad, really bad," Will McCrory said.

Ronnie Stonecipher, fire chief of the Locust Shores Volunteer Fire Department, knew Manley.

"People called him 'Big O.' I don't think I ever heard why, but that was his nickname," Stonecipher said.

Stonecipher said Manley had ridden a motorcycle for a long time.

"I'd see him come by from time to time and I'd see him up at the store on (Alabama) 247 every once in a while. He was a very likable man."
