Dallas ? A daylong standoff between police and a gunman ended Wednesday with the man and two other people dead and four officers wounded. Seven children and a woman held as hostages were released unharmed.

SWAT team officers shot and killed Francisco Fuentes, 32, who kept them at bay for nine hours and fired twice at officers. Fuentes had been in a standoff with police that ended peacefully two months earlier.

A police report said Fuentes broke into an apartment about 2:45 a.m. and fatally shot one man in the chest with a shotgun. He went into a bedroom where the woman and other man were sleeping and shot the man in the head. Fuentes then barricaded himself in the bedroom with the hostages.

Police hadn’t determined the motive in the hostage-taking and killings, and they were questioning the woman who had been held hostage, spokesman Sgt. Gil Cerda said.

The police report identified the woman as Fuentes’ wife, although acquaintances described her as his ex-wife. The men killed were identified as Mario Rios, 30, and John Watson, 31.

When police were summoned to the apartment, the children told them that Fuentes was inside a bedroom with a gun. Fuentes wounded three officers when they entered the bedroom, Cerda said. The officers saw the body of at least one man on the floor.

The officers retreated after they were wounded, and four children were freed at that time.

Over the next few hours, Fuentes released the other three children and the woman, authorities said.

Eventually, police filled the apartment with tear gas, then burst into the apartment. They killed Fuentes when, for a second time, he fired at officers, Cerda said.

All the wounded officers were in good condition.
