The president of the Sigma Chi chapter at the University of Idaho has said that the fraternity is cooperating with the police investigation into the brutal murders of four students.
Ethan Chapin was a member of Sigma Chi and attended a party at the frat house with his girlfriend Xana Kernodle just hours before they were killed. They were at the party from 8pm to 9pm on 12 November before returning to the home where they were killed at around 1.45am.
