More than five decades after 16-year-old Jamie Rochelle Grissim vanished on her way home from Fort Vancouver High School, Clark County detectives are gearing up for a fresh ground search in the forests of eastern Clark County. Investigators are zeroing in on a stretch of woods in Dole Valley near Yacolt, working to determine whether Grissim, who disappeared in 1971, may be buried there.
What investigators say
According to a news release from the Clark County Sheriff’s Office, cold-case detectives recently located and interviewed a long-sought witness tied to the investigation. An “attempt to locate” bulletin for the man was canceled after the interview.
Investigators say the witness’s account “appears credible” and lines up with previously known information about Grissim’s disappearance, particularly details that have long pointed toward the Dole Valley area.
Search partners and methods
The sheriff’s office is coordinating the new operation with Washington State Search and Rescue and Clark County Search and Rescue. Detectives plan to deploy multiple canine teams trained to detect human remains, according to KPTV.
Officials say the specialized dogs are capable of locating remains that may be deeply buried and decades old. The operation is still awaiting final logistical planning and resource availability before teams head into the field.
