5 Disturbing Unsolved Mysteries In Colorado That Will Leave You Baffled

In 1968, Leroy Drieth was leaving his girlfriend's home in Mead when his car slammed into a tree, killing him instantly. It was believed that Drieth committed suicide, but an autopsy performed 25 years later showed that the teenager was murdered (as evidenced by the knife wounds on his neck). To this day, it is unknown who killed Leroy Drieth, but it is speculated that his then-girlfriend has the answer...

In 1984, Mark Groezinger, a beloved community member with no known enemies, was found with multiple gunshot wounds in his car near Lookout Mountain. No official suspects have ever been named; however, there has been continued speculation that his widow was the cold-blooded killer.

Perhaps one of the most perplexed cases of all is that of Roger Dean, a Littleton man who was forced via gunpoint by a masked gunman to tie up his wife. When Dean fled the house for help, he was shot and killed. What baffles police and bystanders alike are the events leading up to the murder: a $30,000 withdrawal by Dean put into a secret account, evidence planted to throw the cops and strange sightings of Dean just hours before his murder. It is still unknown just who shot Roger Dean, but it is speculated that extortion letters delivered to his widow years after his murder were written by both a man and a woman.

In 1999, Nucla autobody repairman Dale Williams vanished into the night after receiving a mysterious phone call from a traveling motorist in need of a mechanic. He was never seen or heard from again, leaving his wife, Diana, to believe that he had been murdered by a former friend--whose ex-wife they had just recently and secretly moved to Colorado.
