Darick James D’Ercole, 58, vanished from Castle Pines, Colorado after leaving his home about 7:30 PM on December 23, 2024 for what was described as a routine bicycle ride. Known to enjoy cycling and to be physically fit, he was last seen wearing a black long-sleeve quarter-zip shirt and blue jeans. He reportedly left behind his wallet and phone. He may have been riding a white and maroon Titus bicycle, though that detail has not been confirmed.

Searches by family and the Douglas County Sheriff’s Office produced no surveillance footage, eyewitness accounts, or physical traces of Darick or his bicycle, and investigators described the early phase of the case as hampered by a lack of evidence. He had a May 2024 arrest for domestic violence, harassment, and menacing; authorities have not established any direct link between that matter and his disappearance. The case is listed in the National Missing and Unidentified Persons System and remains open.

If anyone in Castle Pines or nearby areas saw a man matching Darick’s description, a cyclist on a white and maroon Titus bike, or has other information, please contact the Douglas County Sheriff’s Office.
