Unidentified drones are now being seen with such regularity that even the FBI is struggling to solve the mystery.
Morris County, New Jersey has become the focal point of a bizarre, ongoing aerial mystery that has left both residents and local authorities scratching their heads.
For some time now, drones have been showing up in the skies over the region on an almost nightly basis and nobody has been able to determine who is responsible, what they are doing or why.
Local resident Mike Walsh first started to see the drones back in mid-November and now they are turning up practically every night.
"I'd really like to see one land and report it, but they're up for a long time," he said.
"I don't know where they're taking off from, where they're landing."
Another local - Christian Velasquez - also reported seeing one of the drones.
"It was flying right over this church, continued past the train station," he recalled. "It had three blinking lights. It's weird. There's multiple being spotted at the same time all around Morris County."
"It's definitely concerning."
Local police later issued a statement to allay any concerns that people might have by emphasizing that the drones posed no danger to the general public.
As things stand, it is not only the New Jersey State Police that is investigating the phenomenon but also the Office of Homeland Security and even the FBI.
Whether they will be able to determine who is behind the drones, however, remains to be seen.
