Police: Boyfriend is 'prime suspect' in Chesterfield Twp. teen shooting

The boyfriend of the teen who was shot inside her Chesterfield Township home Monday afternoon is being questioned by police. Police confirm to FOX 2 they are holding the 21-year-old boyfriend on outstanding warrants, and that he is also the prime suspect in the shooting.

At about 3:15 p.m. 17-year-old Marche Lowe was shot in the head inside her home, which is near 21 Mile Road and Gratiot. She is said to be in grave condition.

Police were called around the same time.

Police originally said a witness called 911 about the shooting, but we're now learning the witness is Lowe's boyfriend. Police had been talking to him about what he knew and at one point he even gave investigators a description of a suspect and a vehicle description.
