Xiong, 23, a married father of three children ages 4, 2 and 10 months, had moved to Texas from St. Paul, Minnesota in July.
He was one of 11 siblings whose family came to the U.S. from Laos when he was just a toddler. His family had a history of military service. Xiong's father, Chor Xiong, is a native of Laos who fought the Viet Cong alongside the CIA in 1972; Chor's father, Kham's grandfather, also fought with the CIA; and Kham's brother, Nelson, is a Marine serving in Afghanistan.
"I very mad," Xiong's father said Friday. Through sniffles and tears, he said his son died for "no reason" and he has a hard time believing Kham is gone.
Kham Xiong was preparing to deploy to Afghanistan, and his sister Mee Xiong said the family would be able to understand if he would have died in battle. "He didn't get to go overseas and do what he's supposed to do, and he's dead ... killed by our own people," Mee Xiong said.
