PITTSBURGH — Two teenage residents of a Pittsburgh group home for troubled boys have been charged with criminal homicide in the assault of a third resident, a 16-year-old boy.

Malik Crosby, 16, and Yusuf Shepard, 15, were arraigned Friday on criminal complaints filed Thursday night by city police after the Allegheny County medical examiner's office ruled Nicholas Grant's death a homicide. A preliminary hearing is set for Jan. 28.

An autopsy showed Grant died from a lack of oxygen caused by having his neck squeezed. Grant was removed from life support Wednesday night, four days after police contend he was attacked at the Circle C Youth and Family Services Group Home in the city's Carrick neighborhood, according to the complaints.
