On November 25, 1984, a walker in the lower Poudre Canyon near Fort Collins, Colorado, found the body of 32-year-old Donald D. Ova. A transient who had been living in the Greeley area, Ova was last seen alive on Thanksgiving Day a few days earlier. Larimer County investigators determined he had been led up a hill and shot execution-style; the death was ruled a homicide.

Investigators pursued leads for years. A suspect was identified and scientific testing was done around 2000, but results were inconclusive and the Larimer County District Attorney declined to prosecute. The person reportedly was re-interviewed in 2003 and was uncooperative. No arrests have been made and the case remains an open cold case.

What did the area know about transient populations or visitors to lower Poudre Canyon in late November 1984 that might help explain who was with Ova during those last hours?
