Gordon John Miklethun was 38 when he disappeared from Las Vegas in the winter of 1986. The last confirmed sighting placed him with his parents at an establishment on Spring Mountain, after which he reportedly intended to go home but never arrived. He failed to show up for work the next day and was reported missing to the Las Vegas Metropolitan Police Department.

At the time he went missing Gordon was described as a white male with black hair and blue eyes, about 5 feet 10 inches to 6 feet 0 inches tall and 170 to 180 pounds. Photographs show him with a mustache and he was known to wear a watch. All his personal belongings were left behind and there were no signs he planned to leave, which his family says was out of character.

The case remains open and has been entered into national databases, including NamUs under MP23095. Few investigative leads have been reported and the circumstances of his disappearance are sparse. If anyone saw Gordon the night he left Spring Mountain or has information about his movements afterward, please share what is known.
