Deborah Heriford was 51 when she vanished from Colorado Springs. She was last seen on March 31, 2011, walking her Westie terrier near Academy Boulevard and Vickers Drive. Three days later she failed to appear for her crossing guard shift at Discovery Canyon Elementary School and her husband, from whom she was separated, reported her missing on April 3, 2011.

Her dog was recovered — accounts differ on whether it was found running loose or tied to a post behind a business about a quarter mile from her home. At Deborah’s house on the 2700 block of Maroon Bells Avenue, most things were undisturbed: her car and personal items remained, though her cell phone and keys were missing. Her car had been parked on the street, which was unusual for her. There were no signs of struggle or forced entry.

Deborah was in the late stages of a divorce from Harold Bob Heriford; friends and family said she was scared of him and the divorce was due to be finalized in May 2011. Investigators later treated her disappearance as a homicide. Her children hired a private investigator and police at one point impounded the husband’s girlfriend’s car, but no arrests have been announced.

If anyone knew Deborah’s routines, saw her on March 31, 2011, or has information about her movements that week, please come forward.
