Magisterial District Judge John Murray ordered 23-year-old Niochie Lawson, of Laurel, Md. and 20-year-old Jakal Stone, of Price George's County, to stand trial on charges including robbery and conspiracy.
Prosecutors say Lawson and Stone sought treatment for gunshot wounds following the June 9 ambush, in which one gunman was killed. Police say a bullet taken from Lawson's leg at a hospital matched those fired by Upper Gwynedd homeowner Jermaine Edwards. Investigators say the slain gunman's identification was in the getaway vehicle.
Edwards was shot in the chest and both legs in the attack. Prosecutors say he fired in self-defense and won't face charges.
Lawson and Stone are being held without bail.
