Lyon County deputies say they have finally identified a homicide victim 30 years after the man's body was found in Sand Canyon as 43-year-old Vincent Marion Trapp.

For the past two years, the Major Crimes Division of the Lyon County Sheriff's Office (LCSO) has been actively investigating the unsolved homicide of an unknown man whose body was discovered on March 12, 1992, in Sand Canyon in the southern portion of Lyon County.

The victim had been murdered a year prior to his discovery in 1991 and remained unidentified for 29 years since his death. He had only been known as 'Sand Canyon John Doe'.

In July of 2020 the LCSO Major Crimes Division was able to narrow down a list of potential family members of the victim using genetic database technology and investigative techniques.

From that, LCSO was able to identify him as 43-year-old Vincent Marion Trapp, originally from Sacramento.

Trapp stood 6'6" tall and weighed about 190 pounds with blue eyes and red hair.

After identifying the body and further investigation, LCSO established a rudimentary timeline of Trapp's whereabouts. 

Although they don't know his general whereabouts leading up to his death, authorities do know that Trapp lived in Douglas County from late 1989 to fall 1990, and was a resident of Yerington in the spring of 1991. They believe Trapp was murdered sometime between spring and summer of 1991.

Authorities are now asking for your help in the investigation.
