NEDERLAND, Colo. (AP) — Authorities are studying pieces of an explosive device that was left in a backpack in front of the Nederland Police Department.
Police marshal Paul Carrill says a detective found a backpack outside the building when he began his shift Tuesday morning. He brought the bag inside and found what appeared to be an improvised explosive device.
Two robots searched the backpack, and multiple pieces were removed from the device. The pieces were sent to the forensics lab in Boulder.
Carrill would not say whether police know the backpack's owner. Investigators have not determined a motive.
The police department is in the mountain town's main retail complex, which includes a grocery store and multiple shops. Those businesses were evacuated.
Nederland is located about 15 miles southwest of Boulder.
