A new search is underway in Southwest Washington, focusing on the disappearance of 16-year-old Jamie Rochelle Grissim more than five decades ago. Yesterday investigators with the Clark County Sheriff’s Office conducted a coordinated ground search in the Dole Valley area near Yacolt, focusing on a location identified through new information gleaned last year.
Grissim was last seen on December 7, 1971, after leaving Fort Vancouver High School. Attendance records later confirmed she attended two classes that day before leaving campus. She was never seen again. Early on, investigators considered the possibility that she had left on her own, but her family pushed back, noting she left nearly all of her belongings and savings behind.
About six months after she went missing, her purse and identification were found in a remote part of Clark County, roughly forty-four miles north of Vancouver. Then in October 1974, the remains of two young women, Martha Morrison and Carol Valenzuela, were found within about a mile of that location, with both cases later connected to convicted serial offender Warren Leslie Forrest.
In late 2025, investigators spoke with a potential witness who said they had discovered the remains of a young female in a wooded area around the same time Grissim went missing. The area now being searched sits roughly 1,500 feet from where those 1974 remains were found.
