The Clark County Sheriff’s Office last week announced a breakthrough in a cold case involving skeletal remains discovered in northeast Clark County in 1980.

The department is seeking more information about the suspected person discovered and her family.

The sheriff’s office is seeking information regarding Sandra Renee “Sandy” Morden and her parents, Andrew Bain “Andy” Morden and Kathryn Irene “Irene” Morden. The department has determined that remains discovered along Fly Creek near Amboy in 1980 were that of Sandy Morden, a girl who through investigations by the department they believe went missing in the 1970s.

At the time of the discovery of the remains, the department believed the case to be a homicide. Over the years, attempts to gather more information on the remains, referred to as the Fly Creek Jane Doe before an identification could be made, proved unsuccessful until 2019, when thanks to genetic genealogical data and a process called DNA phenotyping led to the breakthrough, according to the sheriff’s office. The department enlisted the help of Parabon NanoLabs, a Virginia-based DNA technology company, to perform both types of research.

A combination of the phenotyping process, which used DNA to provide the potential appearance of the individual whose remains were found, and genetic genealogy, which used DNA analysis combined with traditional genealogical research, led to the creation of a genetic profile that was compared to public databases used by law enforcement in investigations, the announcement explained. 

Sheriff’s detectives eventually found one family member who told them that Sandy Morden had been missing since the 1970s, providing family history, photographs and a DNZ sample which confirmed the relationship between the Mordens and the Fly Creek Jane Doe.

Now the sheriff’s office is looking to hear from friends, acquaintances, neighbors, coworkers and classmates of Andy, Irene and Sandy Morden, especially those who interacted with the family after 1970. The department provided a brief biography of the family to help spur on the search.

Those with any information are urged to contact Clark County Sheriff’s Detective Lindsay Schultz at or (360) 397-2036.

Sandy Morden’s case was not the first local one to see a breakthrough in 2019 with help from Parabon NanoLabs. The company’s services led for the identification of Richard Knapp as a suspect in the murder of Audrey Hoellein, a 24-year-old cold case, earlier this year, according to an announcement by the Vancouver Police Department at the time of Knapp’s arrest. He is currently expected to go on trial in July 2020 according to the state court database.

About the Morden family

The Mordens were originally from the San Francisco Bay area. Andy Morden was a Marine Corps veteran of the Korean War era and worked in the maritime trades on tugboats involved in the pulp, paper and logging industry on the Willamette and Columbia Rivers.

Andy and Irene Morden divorced in the early 1970s, with Andy Morden assuming custody of his daughter. After the divorce, Irene Morden lived separately at various locations in Portland and in the Bay Area while Andy and Sandy Morden lived in Portland and Vancouver. Sandy Morden attended Binnsmead Middle School (now Harrison Park Middle School) on Southeast 87th Avenue in Portland in 1974 and 1975, Gaiser Middle School on Northeast 99th Street in Vancouver in 1975 and 1976 and Wilson High School on Southwest Vermont Street in Portland in 1976 and 1977. Irene Morden died in 1988 in San Francisco and Andy Morden retired to Ilwaco, Washington, where he died in 1999. The sheriff’s office could not determine Sandy Morden’s whereabouts between 1977 and 1980.
