Oscar Joseph McNear was 30 when he vanished from the Castle Rock, Colorado, area on a summer day in June 1981. Reports indicate he may not have been alone; Cynthia Atterbury was also reported missing about the same time, and their possible joint disappearance is a central but unresolved detail.

Few concrete facts are available about Oscar’s last day. The Douglas County Sheriff’s Office is handling the investigation, and family DNA has been submitted for comparison with unidentified remains databases, but Oscar has not been located.

The case remains open and unresolved. If anyone knew Oscar, Cynthia, or their movements in June 1981, please share what you remember with the Douglas County Sheriff’s Office.
