It seems as though there dispute had been going on for a while but was never reported to police. There’s a few articles that I managed to find but I’ll just link this one: https://allthatsinteresting.com/jeffrey-spaide

Quote from the article and Luzerne Country First District Attorney: “‘Apparently, there’s been an ongoing dispute between neighbors, some of which involved a dispute about snow disposal and removal,” explained Luzerne County First Assistant District Attorney Sam Sanguedolce. “They’re across the street from each other, and when they would remove snow they would throw it across the street at the other person’s property.”

But despite the volatile relationship between Spaide and the Goys, their fights were never reported to authorities. And Spaide was not generally “known to police” — until his final, fatal argument with his neighbors.”
