Around the neighborhood, people fondly called Donehue “The Mayor” and “Pa Pa.”

Crisis responder Andrew Holmes reflected on the loss of Donehue, his cousin, at the place where he was shot.

“We’re still at square one, just trying to get the community to step up those who have eyes and ears see it,” Holmes said.

Williams reports that investigators are looking into the possibility that occupants of a house in the 8200 block of of South Wentworth might have a connection to the shooting.

Police say they can’t reveal additional details, but said they have been to a home on the street where neighbors say police have responded to noise and other problems in the past.

A woman who answered the door at the home identified herself as the owner and told CBS 2 off-camera that there have been no problems involving the police.

City records show the homeowner as a 78-year-old man. He didn’t return calls from CBS.

“I’ve been holding back, fighting back tears,” Holmes said. “It’s tough.”
