Three weeks after four Idaho college students were murdered at an off-campus house, Moscow police say they are still investigating the possibility that one of the victims had a stalker, according to CNN.

Police reported that in October a man appeared to follow Kaylee Goncalves, one of the victims, outside a local business, but the theory was quickly disproved. Police were able to determine that it was an isolated incident and that the man and an associate were trying to meet women at the business. There is currently no evidence linking the two men to the murders, CNN has learned.
Stacy Chapin, 20, Kaylee Goncalves, 21, Xana Kernodle, 20 and Madison Mogen, 21 were found dead on November 13.
A coroner determined that the four victims had each been stabbed multiple times and were likely asleep when the attacks began, police said.
Local, state and federal investigators have begun to reconstruct the timeline, but the mystery still hangs over the circumstances leading up to the murder.
CNN has learned, through Moscow police spokeswoman Rachael Doniger, that officers are beginning to receive forensic test results from the crime scene.
Moscow police also said they received more than 2,000 emails and phone calls from people wanting to provide information to police and more than 1,000 submissions to an FBI link. The killings have worried the approximately 26,000 residents of the city of Moscow since it had not recorded a murder since 2015.
