ST. PAUL, Minn. (AP) — A Minnesota soldier and father of three who had a knack for making people laugh was among those killed when an Army psychiatrist allegedly opened fire on fellow soldiers at Fort Hood, Texas.

Pfc. Kham Xiong, 23, of St. Paul, died in the attack Thursday that left 13 people dead and more than two dozen wounded. The alleged gunman, Maj. Nidal Malik Hasan, was among the injured.

‘‘I very mad,’’ Xiong’s father, Chor Xiong, said Friday. Through sniffles and tears, he said his son died for ‘‘no reason’’ and he has a hard time believing Kham is gone.

‘‘He was a very good son,’’ he said.

Kham Xiong was preparing to deploy to Afghanistan, and his sister Mee Xiong said the family would have been able to understand if Kham would have died in battle. But the death on U.S. soil just didn’t make sense.

‘‘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.
