PHILADELPHIA (AP) -- Police say a Philadelphia man was fatally shot while walking his dog.

Officers found the 51-year-old in the street in the city's Overbrook section with a gunshot wound to the chest around 8:30 p.m. Thursday.

They say he had a dog leash in one hand and a flashlight in the other.

He was pronounced dead a short time later at Penn Presbyterian Medical Center.

Police say the dog remained by the man and wasn't harmed.

They say the man usually walks his dog with his daughter along the same route every night, but that she wasn't there Thursday.

Police suspect the man was the victim of an apparent robbery. They haven't made any arrests. The investigation is continuing.
