The Clark County Sheriff’s Office has used DNA technology to identify the remains of “Fly Creek Jane Doe,” a body discovered near Amboy in 1980, as a girl who went missing from the Portland-Vancouver area years earlier.

Now, deputies are asking for the public’s help on the unsolved case. They’re trying to track down friends, acquaintances, neighbors, coworkers and others who knew the family of Sandra Renee “Sandy” Morden.

Morden’s skeletal remains were discovered Feb. 24, 1980, along Fly Creek near Amboy, according to a news release from the sheriff’s office. “The victim, believed to be female and in her mid to late teens, was the victim of a homicide.”

Three facial reconstructions and multiple media releases over the years were unsuccessful in identifying the remains. However, as a result of DNA and genealogy investigations, detectives determined the remains belonged to Sandy Morden.

Sandy Morden was born 1962, the daughter of Andrew Bain “Andy” Morden and Kathryn Irene Morden. Sandy attended schools in Portland and Vancouver in the mid-1970s, but her whereabouts between May 1977 and February 1980 haven’t been pinned down, deputies said.
