Christopher Luning was 44 when he disappeared from Bridgeton, Missouri, on March 13, 2003. He is described as a Caucasian male, 6 feet 2 inches tall, 225 pounds, with brown hair and brown eyes and a distinctive mole on his back. The Bridgeton Police Department handled the investigation.

Very little is publicly known about his last movements. Reports do not specify what he was wearing, whether he had personal items with him, or any firm leads from the day he vanished. National missing-persons platforms have kept his case listed in hopes of generating tips.

More than two decades after March 13, 2003 the disappearance remains unsolved and his family continues to seek answers. If anyone in Bridgeton or the St. Louis County area remembers Christopher, his routines, or saw anything unusual around that date, please share what you know with investigators.
