Two men are charged with murder, but Detective Sgt. Gregg McKenzie tells the Pittsburgh Post-Gazette the suspects say at least one other person was involved in the fight.
McKenzie didn't immediately return a message Wednesday afternoon.
Twenty-one-year-old Kevin Figaniak of Perkasie, Pa., died early Sunday after an attack on the school campus.
Police charged 22-year-old Craig Peacock of Clewiston, Fla., and 24-year-old Jarrett Chandler of Winnfield, La., with murder. Both remain in the Northern Regional Jail on $1 million bond.
Figaniak was a senior business major who played varsity lacrosse.
A friend who was with Figaniak says they were attacked by three or four men.
