Christopher Casey, 55, is charged with the third-degree murder of 62-year-old Robert Wallace, according to prosecutors.
Authorities said Casey and Wallace were both known to Upper Moreland police for "ongoing arguments, including arguments about the (Casey's) loud snoring, which (Wallace) could hear" through the shared wall of their homes.
Casey told police he was eating dinner around 6:30 p.m. on Sunday, Jan. 14, when Wallace knocked on his window and shouted "I'm gonna kill you!"
Police said Wallace removed the screen and then opened the unlocked window into Casey's home. The pair talked through the window for about 20 minutes and Wallace had "settled down a little bit," Casey told investigators.
Casey said Wallace was "leaning in" through the window during the conversation but didn't try to enter the home. Wallace said he wanted to shake hands and even offered to help pay for corrective nose surgery to help alleviate Casey's snoring, according to the criminal complaint.
Casey said he grabbed a knife, hid it under a blanket, and met Wallace at the door, where he stabbed him "three or four times" in the chest, investigators said.
He called 911 and Wallace was rushed to Abington Hospital where he died just after 7 p.m., police said. He told detectives in an interview that he didn't believe Wallace was serious about shaking hands and working out their disagreement.
The 55-year-old was arrested Thursday, Jan. 18 and his bail was set at $1 million, the DA's Office said. He is due back in court for a preliminary hearing on Jan. 29.
