A rifle used, 30-shots fired, and two people critically injured and fighting for their lives, that's what Saginaw Police found around 5:45 Saturday afternoon in the city's east side.

It happened near the intersection of North 10th Street and Sanford.

An 18-year-old man was shot in the back.

He has life-threatening injuries.

The other victim, a 16-year-old boy, was shot in the head and chest.

Detectives believe someone, if not several people, know exactly who did it.

Sgt. Joseph Dutoi of the Saginaw Police says, "When they got here they found about 100 to 200 people. We're just asking one of those people to come forward and provide us with information on what may of happened up here."

Anyone with information can call 911 or Crime-stoppers at 1.800.422.JAIL.
