Helen Burton, 59, was reported missing from Denver on July 10, 1982 after she failed to board a bus that morning; witnesses last saw her at a bus stop at 5:55 a.m. She was expected at work that day but never arrived. Weeks later, on July 31, a father and his child found her nude body in a park on Deer Creek Canyon Road in Littleton, Colorado, ending the search.

Her death has been classified as a homicide. This remains an open cold case.

If anyone was in the area of the bus stop or Deer Creek Canyon Road in July 1982, or has any information about Helen’s movements between July 10 and July 31, investigators would like to hear from you.
