WEST BLOOMFIELD TOWNSHIP, Mich. â€"  A 74-year-old suburban Detroit woman is in police custody following the shooting death of her 17-year-old grandson.

West Bloomfield Township police Lt. Tim Diamond says officers found the teenager after responding late Friday afternoon to reports of shots fired in the home.

The teen was pronounced dead about 6 p.m. at an area hospital. His grandmother was taken to a hospital for observation. She was to be questioned later by police.

A handgun was recovered at the home, northwest of Detroit.

Diamond says the woman's husband was not at home at the time of the shooting. He adds that officers responded in March to a disturbance at the home and were told the teen's parents live in Arizona.

Diamond was not sure if the teen lived with his grandparents.
