FIRST ON FOX: Blood was seen seeping from the house where four University of Idaho students were brutally murdered over the weekend as a report of a previous campus threat surfaced.

Fox News Digital obtained the grisly new photos of the crime scene Wednesday that showed blood dripping from the first floor bedroom down an exterior wall at the back of the house.  

"It was very bloody scene inside," an officer said.

Back in September, campus security sent out what is known as a "Vandal Alert" to staff and students with the subject line "Threat with Knife" notifying the community of the alarming incident.

"The Moscow Police Department received a report that a group of students was walking between the Steam Plant parking lot (Lot #14) and the Student Recreation Center on Paradise Path and were threatened by a person with a knife," states the alert from Sept. 12. 

A concerned parent of a University of Idaho student shared the notification with Fox News Digital.

"No individual was harmed in the incident, but campus community members are advised to be cautious," the notification states. 

The suspect was described as a White male between the ages of 18 and 22, wearing all black clothes and a black baseball cap, and riding a mountain bike.

The Moscow Police Department declined to comment on the incident, whether the suspect had been apprehended or whether it could be connected to the Nov. 13 quadruple homicides that occurred about one mile away.

"I have no information on that at this time," Capt. Anthony Dahlinger told Fox News Digital. A spokesperson for the university didn't immediately return a request for comment.

Police announced Tuesday that they had not recovered the murder weapon but believe it was likely a knife and called the gruesome killings an "isolated, targeted attack." The released added, "There is no imminent threat to the community."

The shocking murders have left locals and the campus community on edge.

Police have remained tight-lipped but have said the suspect remains at large. Moscow Mayor Art Bettge previously told Fox News Digital that investigators are probing as possible motives a "crime of passion" or a "burglary gone wrong."

"Telling parents there is no threat is not helpful," he said. "Hiring off-duty police is a quick way to put boots and guns where they need to be; protecting students until the suspect is arrested."
