Police say five teenagers were in a vehicle parked on Philip Street just south of Charlevoix Street, near the Detroit border with Grosse Pointe Park, when a late-model tan Cadillac pulled up, and a man got out and started firing an automatic weapon.

As many as 30 shots were fired into the vehicle, one fatally striking Stalker. Three others — a 16-year-old boy, a 15-year-old boy and a 16-year-old girl — received gunshot wounds. A 15-year-old girl who was uninjured in the gunfire jumped into the driver’s seat and drove her friends to a nearby hospital.

Detroit police chief James Craig said that he wants to see the case solved.

“Some cases we can close rather quickly, it just depends on what evidence we have, it depends on witnesses, and certainly this is a challenging case,” Craig said.
