A Milwaukee teenager is charged with first-degree intentional homicide in the shooting deaths of two men during a robbery.

The Milwaukee Journal Sentinel reports 18-year-old Richard Littlejohn Jr. also was charged Thursday with use of a dangerous weapon in the deaths of 34-year-old Willie Shankle and 32-year-old Darius Parker, both of Milwaukee.

According to the complaint, a witness told investigators that on April 21 Litteljohn went to an apartment on Milwaukee's north side, where Shankle talked about buying a gun.

The complaint says Littlejohn then pulled a .22-caliber handgun from a backpack and shot Shankle six times before shooting Parker four times. Littlejohn then took money from Shankle's pants pocket and fled.

Littlejohn is in the Milwaukee County Jail. Online court records do not list a defense attorney.
