A teenager shot his former girlfriend four times outside her high school Wednesday, then killed himself, police said.

Jessica Forsyth, 17, was taken to Hurley Medical Center in Flint, where she was in serious but stable condition, hospital spokeswoman Christie White said Wednesday afternoon.

Midland Police Chief James St. Louis said the gunman died in the parking lot.

The boy, a 17-year-old from Coleman, had gone to H.H. Dow High School on Wednesday morning to try to talk to Jessica, but he was turned away by school officials, the police chief said. The boy then called her and asked her to meet him outside the building.

After a conversation in the parking lot, the boy pulled a gun out of a backpack and shot her four times before turning the gun on himself, St. Louis said.

The girl's mother, who had dropped her daughter off at the school, saw the shooting from her car and drove between the two to try to protect the girl, authorities said.

The school, about 100 miles northwest of Detroit, was locked down after the shooting. Dow High is named after the founder of chemical giant Dow Chemical Co. and has 1,500 students.
