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

Police said a man appeared in October to follow Kaylee Goncalves, one of the victims, out of a local business, but the theory was quickly debunked. Police were able to determine that this was an isolated incident and that the man and an associate were trying to meet women at the firm. 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 reconstructing the timeline, but mystery still looms over the circumstances leading up to the murder.
CNN has learned via Moscow police spokeswoman Rachael Doniger that officers are starting 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 referrals to an FBI liaison. The killings have worried the approximately 26,000 residents of the city of Moscow as there has not been a single homicide since 2015.
