It's possible. According to WTOL
"Toledo police tell AMW that the shooter is believed to be a black male, approximately 6' to 6'6" tall, and he may have been wearing a black sweat suit. Witnesses say they saw him running across Western Ave. towards South Ave. right after the shooting."

It's possible that the shooter was a jogger, who, like others in this thread packed heat while jogging and that perhaps Mr. Babcock, a newbie cyclist, came too close in a crossing. The only thing taken from Mr. Babcock were his keys. A mugger would have taken the wallet. It's very sad. Here are several stories about it.
