Samuel Junior, a 68-year-old Vietnam veteran, was found dead in the apartment he shared with his longtime girlfriend, Linda.
Linda, who declined to give her last name when she spoke to 7 Action News Tuesday afternoon, said she heard the gunshots, but didn't call 911 because Junior told her he was "alright."
"Sweet man. Never did nothing to nobody," is how Neighbor Debbie Brassfield described Junior.
Brassfield said it was late Tuesday morning when Linda began banging on her door and another neighbor's door, calling for help, telling them "Sam's been shot."
But when Brassfield and another neighbor rushed to check on him, it was clear Samuel Junior had been dead for some time. Brassfield says that's when Linda told her, Junior had been shot last night.
Linda told Brassfield that she didn't call 911 right after Junior had been shot because there wasn't much blood.
Linda told 7 Action News that Detroit Police were looking for her son and that she believed he shot Junior.
Late Tuesday afternoon, Detroit Police would only confirm that they had a suspect in custody.
