A 15-year-old boy in Billings, Mont., died early Sunday morning after he tried to wake his friend by throwing rocks at his bedroom window but was shot in response.
Mackeon Schulte died from a bullet wound to the head at about 2:30 a.m. Another boy escaped without injury, according to the Billings Gazette.
Police have ruled the death an accident.
Schulte and his friend were apparently at a sleepover when they decided to visit the shooter's house. In an attempt to wake the sleeping teen, the two boys knocked on his window and threw pebbles at his room. But he reportedly became frightened by the noise, grabbed a revolver and fired through the window.
No arrests have been made but investigators will be meeting with Schulte’s family and local officials to determine if charges will be filed.
“It’s a tragedy. We have to investigate at this point for what it is, but it’s a tragedy all around,” said police captain John Bedford.
