Who murdered Dennis Oscar Lingaas in 1993? In the spring of 1994, the quiet of the forest in Jefferson County, Colorado, was broken by a grim discovery. On April 7, a U.S. Forest Service worker stumbled upon human remains in the vicinity of Forest Service Road 695 and County Road 96. These remains would later be identified as those of Dennis Oscar Lingaas, a 48-year-old male who had vanished nearly a year earlier.
His case is officially classified as a homicide.
The story of his disappearance began on June 5, 1993, when his roommates in Denver reported him missing. A few days later, on June 8, a significant clue surfaced when Lingaas's 1973 Buick was found abandoned in the middle of a roadway in the same remote area where his remains would eventually be located. This discovery hinted at a troubling and mysterious end to his life, leaving more questions than answers for investigators.
Despite the passage of time, the investigation into the death of Dennis Lingaas remains an open and active cold case with the Jefferson County Sheriff's Office. To date, no suspects have been publicly identified, and no arrests have been made in connection with his murder. The circumstances surrounding his disappearance and death continue to be an unsolved puzzle, leaving his family and friends without closure. Authorities continue to seek information from the public that might shed light on this long-unsolved homicide.
