Suicidal man accused of using gun to rob ammunition from Longmont Walmart surrenders after standoff

Police: Kevin Aguirre, 19, threatened suicide

LONGMONT, Colo. - Longmont police say a 19-year-old man accused of using a handgun to rob ammunition from a Walmart on Tuesday night surrendered peacefully after a 90-minute standoff during which he threatened suicide.

Kevin Aguirre was arrested around 9 p.m. on investigation of aggravated robbery, said Longmont Police Cmdr. Jeff Satur.

The incident began about 6:52 p.m., when a man armed with a black 9mm handgun demanded ammunition for the gun from the sporting goods department at the Walmart Supercenter near U.S. Highway 287 and Ute Highway, the Longmont Times-Call reported. Police said he left the store with about 50 rounds of 9mm ammunition.

After the robbery, Satur said Aguirre was found at a trailer-home park at 1400 S. Collyer St. A standoff ensued and the teen, who still had the handgun, threatened suicide, police said.

Police negotiator Chrystie Wheeler persuaded the distraught gunman to surrender without harming himself, Satur said.
