A shooting at the University of Michigan Tuesday killed three people and critically injured five others, according to police.

According to the Volusia County Sheriff’s Office, the shooting happened during a confrontation between a man and a friend who lived on his property. “The shooter, a 34-year-old man, contacted law enforcement and remained on scene to provide his account of the incident,” deputies said. Deputies said the shooter and his friend were outside the home when his friend pointed a pitchfork at him in a threatening manner. The man then told authorities that his friend “advanced toward him aggressively” with the pitchfork and he fired his gun. “The shooter told detectives he was in fear for his life and his wife’s, as she was inside the residence at the time of the incident,” deputies said.
