GRETNA, Neb. (AP) — Authorities say a dispute led a man to shoot another man in a Gretna apartment complex parking lot, then fatally shot himself.

The Sarpy County Sheriff’s Office says the shooting happened around 8 a.m. Thursday, when 50-year-old Michael Bartenhagen, of Gretna, was shot two to three times while he was in his vehicle. Investigators say Bartenhagen drove himself to a nearby fire station and was then taken to an Omaha hospital in serious condition. He’s expected to recover.

Deputies say they found the suspect, 52-year-old Scott Rieflin, of Gretna, in his apartment suffering from a self-inflicted gunshot wound. He was taken to a hospital, where he was pronounced dead.

Investigators say the two men knew each other and that Rieflin was upset about a relationship between Bartenhagen and a woman.
