A three-vehicle crash at the end of a police pursuit that injured seven people began with a triple shooting that wounded three juveniles, police said Friday.

According to police:

Two girls, ages 13 and 16, and a 14-year-old boy suffered injuries that were not life-threatening when they were shot shortly after 3 p.m. Thursday in the 4600 block of North 36th Street.

A 14-year-old boy was arrested at the scene, but the victims of the shooting were uncooperative.

The driver of a vehicle involved in the shooting caused a crash involving a school bus and a pickup truck about 3:30 p.m. in the 4000 block of West North Avenue after fleeing from an attempted traffic stop.

A woman and a 13-year-old boy on the school bus and the occupant of the pickup truck were hospitalized with injuries that were not life-threatening, police said in a news release.

The four occupants of the suspect vehicle fled before being arrested and taken to hospitals, including one who suffered life-threatening injuries, police said.

No further details were available Friday afternoon.

The shooting Thursday makes for five children hit with gunfire in the last three weeks.

Tuesday night an 11-year-old girl was struck with a bullet shot through a window of a home on the 2900 block of North 44th Street. The girl had injuries that were not life-threatening.

And on March 29 a 7-year-old girl was hit with a bullet while sitting in a car outside a home on the 4600 block of North 28th Street during a confrontation between two men. Prosecutors say the man who shot the girl sexually assaulted her earlier that morning, and the confrontation began when the girl told her mother about the assault. The girl survived her gunshot wound.

The string of children hit by gunfire comes after the November shooting death of 13-year-old Sandra Parks, hit with bullets that shattered her bedroom window on the 2700 block of North 13th Street, sparked a citywide outcry about violence in Milwaukee. Sandra was at least the fifth Milwaukee child fatally shot inside a home in the last four years by gunfire that erupted outside.
