GILCREST, Colo. -- The all-clear was given and residents were allowed to return to their homes in Gilcrest after a suspicious backpack forced an evacuation on Monday night.
The Weld County Sheriff's Office said the backpack was found at Valley High School about 7:30 p.m.
It had wires coming out of it and it was making beeping noises.
The entire town of about 1,000 people on U.S. Highway 85 about 10 miles south of Greeley was evacuated while the bomb squad was called in.
Law enforcement went door to door to tell everyone to evacuate to a safe place. A reverse emergency notification call was sent out as well.
About 11 p.m., officials determined the backpack was not a threat and the all-clear was given.
A spokeswoman with the Platteville Police Department said it turned out the backpack was a locating device, which is used to find underground cable and utility lines.
It's not clear why it was left in a backpack and unattended at the high school.
