Texas man Tan Do kills self after shooting wife, Five Others

An enraged husband killed his wife and several of her relatives before tuing the gun on himself at his 11-year-old son's birthday bash at a roller rink on Saturday, police said.

No children were killed during the rampage that left six dead, including the gunman, 35-year-old Tan Do, authorities said. Four others were wounded.

"This was a domestic situation that went south in a hurry." Grand Prairie Police Department spokesman John Brimmer told Reuters. "The shooting lasted only seconds."

The couple had been having ongoing marriage problems that investigators believe led to the shootings about 7 p.m. Saturday at Forum Roller World in Grand Prairie, about 20 miles west of Dallas.

None of the young ones, including Do's 11-year-old son and another child, were hurt during the incident. It is believed that the man ordered all of the children to leave the party, then waited until they were gone before opening fire.

Do killed his 29-year-old wife, Trini Do, as well as her sisters Lynn Ta, 16, and Michelle Ta, 28, and 21-year-old brother, Hien Ta. Trini's sister-in-law, Thuy Nguyen, 25, was also gunned down, police said in a statement.

"They just looked terrified," witness Cody Poston WFAA 8 News in Dallas/Fort Worth. "There's several people crying. The kids were just kind of oblivious."

The police department has made crisis counselors available for victims and witnesses.

"[This is] a great city and for something like this to happen is just horrible," Brimmer said.
