Two teen residents of a Pittsburgh group home have now been charged with criminal homicide in the assault of a third resident, a 16-year-old boy.
The Allegheny County medical examiner's office on Thursday ruled Nicholas Grant's death a homicide, after determining he died from a lack of oxygen caused by having his neck squeezed. Grant died days after Saturday night's attack at the Circle C Group Home in the city's Carrick neighborhood.
And online court records show police have now charged a 15-year-old and 16-year-old with criminal homicide, on top of aggravated assault and conspiracy charges they already faced.
The teens were still awaiting arraignment early Friday.
The defendants are charged as adults, but The Associated Press generally does not identify minors charged with crimes. Court records don't list defense attorneys.
