Human skeletal remains found by hikers west of Red Rocks Amphitheatre on December 14, 2012 were later identified by forensic analysis and DNA as Lorne Mabbutt, born August 13, 1972. Mabbutt had been reported missing from the Morrison area on October 2, 2005, and investigators judged his disappearance suspicious. The Jefferson County Sheriff’s Office classified the matter as a homicide and recovered the remains from the remote site; however the exact cause of death could not be determined.

Despite an active investigation at the time of identification, no arrests or publicly identified suspects have been announced and the case is now considered cold. What details do readers remember from Morrison in 2005 or the Red Rocks area that could help investigators reopen leads?
