There are claims that one of the victims had a stalker.
The bodies of four University of Idaho students were found the morning of November 13th.
The suspect in the attack has not been identified by police. Four of the victims bled out from their wounds when they were asleep.
The two roommates who called police were not involved in the crime and are still looking for a suspect.
Police have not been able to verify or identify a stalker after looking into information they received about a stalker.
The public is being asked to give police information about the stalker and the general case.
The online discussion about the terminology used to describe the weapon in their deaths was noted by police.
The type of knife used in the attacks is believed to be a fix-blade knife. The detectives are still looking for the weapon.
Police said the surviving roommates called friends over to the house because they initially thought one of their roommates had died.
The night before their deaths, Mogen and Goncalves stopped at a food truck and took a ride home from a private party driver.
Police have said that all four returned home around 1:45 a.m. on Nov. 13 after going to a party at a Fraternity house.
The four were killed in the middle of the night.
The driver and another man seen in a video with the two at a food truck have not been ruled out as suspects. A person called seven times from the cell phone of a woman after she came home.
The person was sleeping and not getting calls, according to the person's mother. They would have called the police. They wouldn't have called him.
