Two of five young people stabbed to death at a house party celebrating the end of classes at the University of Calgary have been identified.
Zackariah Rathwell and Josh Hunter were members of a local band called Zackariah and the Prophets.
Jesse Northey helped produce their first album and described the pair as talented, friendly guys.
Northey was at the band's album release show Saturday night at a Calgary bar, and says its a shame the two were killed.
Police say the suspect in the worst mass murder in Calgary's history is the son of a senior officer.
Local media reports have identified the alleged attacker as Matt de Grood, a 23-year-old student at the U-of-C.
A Facebook page under the same name says he completed a psychology degree and had been accepted into law school for the fall.
Police say they don't yet know what motivated the crime and first-degree-murder charges are pending.
