Mysterious drones flying nighttime patterns over northeast Colorado leave local law enforcement stumped

The drones, estimated to have six-foot wingspans, have been flying over Phillips and Yuma counties every night for about the last week, Phillips County Sheriff Thomas Elliott said Monday.

“They’ve been doing a grid search, a grid pattern,” he said. “They fly one square and then they fly another square.”

The Federal Aviation Administration told the sheriff’s office that it had no information on the drones, and the U.S. Air Force said the aircraft aren’t theirs, Elliott said.

Even if the sheriff’s office identified the pilot or pilots of the drones, they’re likely not breaking any laws, Myers said.
