Authorities said they’re investigating a case of domestic violence that ended with a man dead and a woman injured in South Dakota, and the suspect fleeing through Wyoming before killing himself Saturday in Colorado.

Deputies responded to a report of a homicide around 9:45 p.m. Friday at a home on U.S. Highway 16 west of Custer in far western South Dakota. They found a man dead there, while a woman who was assaulted in the incident drove herself to a hospital, South Dakota Attorney General Marty Jackley said in a news release.

The suspect fled the scene into Wyoming. He was eventually stopped early Saturday after a pursuit in northern Colorado, where he died of a self-inflicted gunshot wound, the Larimer County, Colorado, Sheriff’s Office said in a separate statement.
