CHICAGO (CBS) -- A 16-year-old boy is charged with murder and armed robbery following a shootout with Chicago Police that left another teen suspect dead Wednesday night in the South Shore neighborhood.

The boy, whose identity was withheld because he is a juvenile, was charged at 6:15 p.m. Thursday night with first degree murder and armed robbery with a firearm, police News Affairs Officer Robert Perez said.

He is scheduled to appear in bond court later Friday, Perez said.

The incident unfolded about 8 p.m., when two Chicago Police sergeants were stopped by a person saying that two people just committed a robbery in the area of East 70th Street and South Cregier Avenue, police said.

The sergeants saw two people matching the description and ordered them to stop, police said. One of the suspects armed with a weapon in his hand turned in the sergeant's direction. The sergeant then shot the suspect, later identified by the Cook County Medical Examiner's office as 15-year-old Tatioun Williams.

Williams, of 1311 E. 69th St., was pronounced dead at 8:40 p.m. by authorities at Northwestern Memorial Hospital, according to the medical examiner's office. An autopsy Thursday found he died from a gunshot wound to the back and ruled the death a homicide.

The second suspect was arrested, police said. A weapon and proceeds from the robbery were recovered at the scene.

No one else was injured, police said.

A spokesperson from the Independent Police Review Authority, which investigates all police-involved shootings, did not return calls seeking comment.
