A southeast Alabama man was killed in a dog attack while he was out walking.

Phenix City police were dispatched at 2 a.m. Tuesday to the 100 block of 17th Avenue on a report of a dog bite, said Capt. Darryl Williams. When officers arrived on the scene, they found the 70-year-old victim on the ground with a serious injury to his left arm.

Frank J. Cobb was treated on the scene and then transported to Piedmont Columbus Regional Hospital. He was later moved to an Atlanta hospital where he died.

Williams said officers searched the area for the animal but had no luck in finding it at the time of the incident.

A dog was later discovered on U.S. Highway 431 South, dead after being struck by a vehicle. That dog matched the description of the animal that attacked Cobb and was a pit bull, Williams said.

The dog was sent to the lab for testing.

Williams said the investigation is ongoing.
