UFOs aren't the only unexplained oddity happening in Roswell these days. A worker at an Albertsons grocery store in the New Mexico city found a loaded pistol inside a package of frozen meat.

So far, law enforcement officials tell local affiliate KRQE-TV that they have no idea where the gun came from. The Albertsons employee turned over the .38 Super, which was loaded with seven rounds of ammunition.

"I have personally never heard of this," Sgt. Jim Preston of the Roswell Police Department told the station.

Police say the frozen meat came from the Swift meatpacking plant in Greeley, Colo., and is dated June 8, 2011.

"We could speculate on a lot of things," Preston said. "It could have been someone just dropped it there, or it could have been something that someone put in there trying to hide it for 100 different reasons."

Both Colorado and New Mexico police say the gun has not been reported stolen. Unfortunately, the Albertsons employee wiped down the gun before handing it over, meaning there are no fingerprints or other evidence for police to collect in their investigation. Still, they are able to use the gun's serial number to track it to the last location from where it was sold.

"If we would have been notified while it was still in the box and no one would have touched it, there could have possibly been some forensic evidence that we could have actually looked into," Preston said.
