More than a month since Kaylee Goncalves, Madison Mogen, Xana Kernodle and Kernodle’s boyfriend, Ethan Chapin, were found dead in an off-campus house in Moscow on November 13, police have yet to identify a suspect or make any arrests.

Inan Harsh, 30, who lives in an apartment complex a few doors down from the house, told the Idaho Statesman earlier in December that he had gotten home from his job as a cook at a restaurant in Pullman, Washington—his hometown, which is located less than 10 miles from Moscow—at around 1:30 a.m. on the night of the murders.

The newspaper reported that Harsh said he couldn’t be sure, but thinks that he heard a scream from the vicinity of his neighbors’ home when he was dozing off at around 4 a.m.

It didn’t grab his attention, he said, because he assumed it was a “party sound.”

“I didn’t think anything of it,” Harsh said. “After what happened, I’ve definitely had second thoughts. Maybe it was not a party sound.”

He added that he didn’t mention the detail to police during an initial conversation with an officer. “I’m not sure what good it does for them now,” he said.

Harsh has also written about the murders on social media, taken part in a Reddit “Ask Me Anything,” been interviewed on YouTube and also referenced the murders in TikTok videos on his channel, leading to him continuing to be discussed online in association to the case.

In his lengthy introductory post on the Reddit AMA, Harsh described the victims as “beautiful, friendly, kind, and joyful.”

Harsh wrote that when an officer knocked on his door and asked if he had heard anything on the night of the murders, he “was like no, nothing unusual.”

“I didn’t know there was a murder so small [details] like a faint scream in the distance, one of my neighbors getting home, closing their car door, closing [their] front door, etc were not on my mind,” he wrote.

“I heard a scream, faint and party like to my half asleep eyes. To be clear theres probably at least 5 screams every saturday.”

He also discussed his own life at length, including his history of drug use and past convictions, saying it was one that many “will judge and consider immoral.”

Newsweek has contacted Harsh for further comment.
