Ian Kirk Willcoxon was 24 years old when he disappeared from Boone, Colorado, on January 4, 2017. Despite years of investigation, his whereabouts remain unknown, and there has been no confirmed contact with him since the morning he vanished.

Ian was last seen at the residence where he was living with a friend in the 2300 block of 57th Lane in Boone, Colorado. He also spent part of his time living in Conroe, Texas. According to investigators, the only belongings missing with Ian were the clothes he was wearing, his cell phone, keys, wallet, and firearm.
