OMAHA, Neb. (AP) — Sheriff’s officials say a nearly 12-hour standoff in a west Omaha house ended with the deaths of three men, including that of the shooter.

Douglas County Chief Deputy Sheriff Thomas Wheeler says the standoff began Friday morning when 45-year-old Kenneth Clark’s ex-girlfriend came to his house with her brothers to collect her belongings. Wheeler says a call made to 911 to report a shooting sent law enforcement officials to a house. After several hours of negotiations, police say Clark released his ex-girlfriend, Julie Edwards, unharmed.

But Wheeler says Clark refused to surrender. Around 10 p.m., officers fired tear gas into the house. Shortly afterward, officials heard a gunshot and discovered Clark dead from a self-inflicted gunshot. The bodies of Jason Edwards and John Edwards were found in the house.
