A man who lives near the home where four University of Idaho students were killed last month has come forward about hearing a scream early on the morning of the attacks in the area of the crime scene, according to a local report. 

Inan Harsh, a local chef, told the Idaho Statesman he got home around 1:30 a.m. on Nov. 13 after working late. The home at 1122 King Road in Moscow, Idaho, was usually bustling, even at that time, he told the news site, but instead, "There was not a lot of activity." 

Hours later, as he began to fall asleep around 4 a.m., he said he heard what sounded like a scream coming from the area of 1122 King Road, the Statesman reported. However, Harsh reportedly did not think much of the scream and instead associated it with a "party sound" rather than one of more negative value.

"I didn’t think anything of it," Harsh told the news site. "After what happened, I’ve definitely had second thoughts. Maybe it was not a party sound."

He reportedly said he did not initially tell police about the sound, adding, "I’m not sure what good it does for them now."

A Facebook page that appeared to belong to Harsh included a post from Nov. 15 stated: "4 killed in stabbing across street. No screams,no evidence, no trace. So like, professional killers? But why, on 3 soroiy [sic] girls?"
