A Colorado man last seen taking a walk with a family member on the dam above Chatfield Reservoir at Chatfield State Park near Littleton is missing, according to the Jefferson County Sheriff’s Office.

Adam Padilla, 30, was last seen with a family member at about 7:30 p.m. on Monday night. The family member reportedly headed back to their vehicle, while Adam continued walking. That same family member then called the sheriff’s office when Adam never returned to where the car was parked.

The sheriff’s office has since completed an extensive search of the area, but Adam was not found.

Authorities have now asked the public for help in finding Adam, who has been described as a 5-foot-8 185-pound Hispanic male with brown eyes and black hair. He was last seen in tan khaki shorts, a navy blue shirt, and a black beanie.

Anyone with information should call 303-271-0211.
