The Mesa County Sheriff's Office says students at Orchard Mesa Elementary School did the right thing by telling an adult they thought they had seen guns on campus yesterday.
The students say that late Monday afternoon a hispanic man and a black man threatened to shoot several students playing on the playground.
School District Spokesman Jeff Kirtland says the incident happened after school hours, and that students and teachers had already gone home for the day.
He says investigators are looking into the possibility it was a group of neighborhood kids who were on the playground after school.
The Sheriff's Office canvassed the neighborhood and found nothing to substantiate the claim, but investigators say there's nothing that indicates the children were lying.
Investigators say they may have seen something they thought was a gun.
At this point the investigation is ongoing and school is continuing as normal.
