BOISE, Idaho (NEWSnet) — As hundreds of students mourned together inside the University of Idaho's stadium Wednesday night, family members of four slain classmates urged them to raise their eyes from grief and focus on love and the future.

Four people were stabbed to death Nov. 13 at a rental home near campus in the quiet university town of Moscow, Idaho, and law enforcement has yet to name a person of interest in the case.

Little new information has been released about the investigation into the killings. A county coroner said the four were likely asleep when they were attacked. Investigators have yet to find the fixed-blade knife used in the killings.

Gov. Brad Little announced last week that he was directing up to $1 million in state emergency funds for the investigation. The FBI has assigned 44 people to the case — half of them stationed in Moscow — and the Idaho State Police has 15 troopers helping with community patrols and another 20 investigators working the case.
