Several neighbors said Craddock was clean cut, a member of the neighborhood association board and spent time lots of time at the gym. But they also said he mostly kept to himself, especially after his wife left him some number of years ago.

Angela Scarborough, who lives in the neighborhood, said “he was very quiet . he would just wave.”

She said she knew his wife, but she left some time ago. “She just left,” Scarborough said. “Didn’t let us know or anything.”

“I’m very saddened because this is a great neighborhood,” Scarborough said. “It’s very sad to know that that’s the way he decided to resolve the situation. It’s just something I can’t believe.”

She added: “I would speak to him and he would speak back, but conversation-wise, I never had a conversation with him.”

Cassetty Howerin, 23, who lived under Craddock, was visibly shaken upon learning from reporters that police said he was behind the shooting.

“That could have easily been me,” she said.

Howerin said Craddock had cameras at his home monitoring two nice cars parked out front, including what appeared to be a Mustang. But she said she never saw him bring anyone over. She never saw him come home with groceries.

“He never really cracked a smile,” she said.

She said he seemed to be up at all hours of the night, walking around his apartment and sometimes dropping heavy things on the floor above her apartment. She also said that he was “jacked” from spending a lot of time at the gym.
