An Independence man faces a felony charge after he allegedly threatened to shoot staff at a Kansas City school where his step-child attends.

Samnang Duong, 40, has been charged in Jackson County Circuit Court with first-degree terroristic threat. According to court documents, three staff members at Whittier Elementary School in northeast Kansas City told police on Jan. 19 that they were in a meeting when Duong arrived at the school earlier that day and shouted profanities at them, demanding to know who had called the Department of Family Services regarding his step-son.

“If I find out who hot-lined my family, I will come up to the school shooting,” one witness told police Duong said. He then said he didn't care about going to jail and to “Check my history.” Another witness told police Duong said “I'll shoot you,” to each of them.

According to court records, Duong pleaded guilty in Platte County in January 1996 to two counts each of first-degree assault and armed criminal action and was sentenced to 10 years in prison.

Duong was arrested Thursday on a felony stop. According to court documents, he told police about several incidents involving Whittier Elementary which he did not feel were handled properly. He said he was in a meeting at the school with the victims and did get upset but denied that he threatened to “Shoot up the school.”
