74-year-old grandma accused of shooting 17-year-old grandson to death

Police say a 74-year-old Detroit grandmother shot and killed her 17-year-old grandson, MyFoxDetroit reports.

Jonathan Hoffman was shot several times but managed to call 911, police say. He later succumbed to his injuries at a local hospital.

Authorities took the teen's 74-year-old grandmother, who has not been named publicly, into police custody. They told MyFoxDetroit the woman was not cooperating with authorities.

MyFoxDetroit reports Hoffman had moved into the condo his grandmother shared with Hoffman's 86-year-old grandfather about six months ago. Police believe the two had a volatile relationship, and authorities had responded to a domestic violence dispute in March.

One local teen who identified himself only as a friend of Hoffman's told MyFoxDetroit Hoffman was a good person.

"He was a great friend," the teen told MyFoxDetroit. "He was always there for me if I had any problems, but honestly like I'm shocked."
