A Florida man killed himself after taking hostages in his ex-wife's Irving home Monday morning, police say.

Irving police received a call about a domestic disturbance and shots fired around 9 a.m. in the 300 block of San Marcos Drive, near Las Colinas Boulevard and the Bush Turnpike, spokesman James McLellan said.

Three people ran from the house when police arrived, McLellan said. A SWAT team surrounded the home, and eventually two more hostages were rescued — leaving just the gunman inside — he said.

Dzung Cong Phan, 68, of Largo, Fla., died of a self-inflicted gunshot wound, McLellan said. Authorities found his body after shooting tear gas into the home.

No one else was injured, McLellan said.

Police said Tuesday that Phan had gone to the home to try to reconcile with his ex-wife, then returned later with the intention of killing her and her family.
