CUSTER, S.D. (AP) — 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.

The sheriff’s office said it was notified around 2 a.m. Saturday that the suspect was driving a pickup truck toward Colorado from Cheyenne, Wyoming. Law enforcement tried to contact him, but he eluded officers as he drove south on Interstate 25. Attempts by deputies and state troopers to stop him with tire spikes near the Buckeye exit failed, and the suspect shot at officers, the sheriff’s office said.
