Idaho murders: Neighbor says he heard a SCREAM at 4am on night of attack but 'didn’t think anything of it'

Who is Jack DuCoeur? Kaylee Goncalves called her ex-boyfriend several times on night she was killed

Inan Harsh, 30, a native of Pullman, Washington, reportedly said that he resided in the apartment building next to the victims' home for roughly two years. Harsh said in an interview, "It was kind of bizarre. There was not a lot of activity." He believes he heard a scream early that morning from close to his neighbor's house, but he claimed that he did not pay much attention to it because he perceived it as more of a "party sound," which was not unusual given the circumstances.

Harsh reportedly said, "After what happened, I’ve definitely had second thoughts. Maybe it was not a party sound. I’m not sure what good it does for them now," adding, "I'm not sure what good it does for them now." 

Earlier, Harsh had put up a status on Facebook on November 16 that read, "4 killed in stabbing across street. No screams,no evidence, no trace. So like, professional killers? But why, on 3 soroiy girls? S**t doesnt make sense." Police may reportedly call in Harsh for questioning again, as per News Nation.

On December 1, police reiterated their concerns about the incident, although they were still unsure about whether it was a targeted attack or not. Authorities have, meanwhile, asked people to come forward with any relevant information.
