Gunman Kills ex-wife, bystander in Texas ( carry permit holder dies saving others)
TYLER, Texas (AP) -- A man angry about being sued for unpaid child support opened fire with an AK-47 assault rifle outside a courthouse, killing his ex-wife and a man trying to help the couple's adult son.
The gunman, 43-year-old David Hernandez Arroyo Sr., was killed Thursday afternoon in a gun battle with officers a few miles away after wounding his son and three law enforcement officers, one critically.
The son had been acting as a mediator between his parents, police said. Police estimated that Arroyo, who had a history of spousal abuse and weapons violations, shot 50 rounds in the historic town square. He was wearing a military flak jacket and a bulletproof vest. "He definitely came well-armed and prepared," police Chief Gary Swindle said. "We do understand there had been some threats made by him the previous week."
But the attorney representing Maribel Estrada, 41, said he doesn't believe she thought her ex-husband was dangerous. Estrada worked at a meat packing plant in Tyler and raised a 17-year-old and a 6-year-old with the help of her eldest son, Joshua Wintters said.
The other victim, Mark Alan Wilson, 52, was credited by authorities with saving the life of David Hernandez Arroyo Jr., who was listed in fair condition at a hospital with leg wounds. A sheriff's deputy, Sherman Dollison, 28, was in critical condition after being shot in the liver, lungs and legs; a sheriff's lieutenant and a Tyler police detective were treated and released.
"One of the deputies at the scene said if it hadn't been for Mr. Wilson," said Sheriff J.B. Smith, "the son would be dead."
