Poor girl, just coming home from school... a beautiful, talented girl who had the misfortune of finding herself in Warren's trash... All I can say is that I hope one day your remains can be found and laid to rest properly. Rest in peace, little Jamie.

DNA could hold the key to closing decades-old Clark County cold case murders

For decades, Warren Forrest has lived behind bars after being convicted of killing two women. Detectives believe he is tied to many more victims.

Maas has investigated these disappearances for decades. He’s long believed Forrest is tied to the deaths or disappearances of Jamie Grissim, Barbara Derry, Diane Gilchrist, Gloria Knudson and Carol Valenzuela. He has not been charged in any of their deaths or disappearances.
"Forrest shows up in town in early 1971,” Maas said. “And this series of disappearances and homicides end on the day that he's arrested."

Update just disseminated by Clark County Sheriff’s Office:

UPDATE ON INVESTIGATION OF 1970S COLD CASES LINKED TO SERIAL KILLER WARREN FORREST​

News Release from Clark Co. Sheriff's Office
Posted on FlashAlert: December 5th, 2025 8:19 AM

The Clark County Sheriff’s Office Major Crimes Unit is cancelling the “Attempt to Locate” bulletin issued earlier this year regarding 72-year-old Matt (Mathew) W. McClure. The bulletin was disseminated initially as part of the ongoing investigation into the 1971 disappearance of Jamie Grissim, believed to be an early victim of convicted serial killer Warren Leslie Forrest.

The Clark County Sheriff’s Office Cold Case Team sought the public’s assistance in locating Mr. McClure because he was believed to have information relevant to Grissim’s disappearance, based on a possible sighting in the winter of 1971. McClure was never considered a suspect in this case. Due to his believed association with the local unhoused community, locating and contacting him required assistance from the public.

Thanks to tips received from the community, investigators successfully located and interviewed Mr. McClure.

While the details of the interview remain part of an active investigation and are not being released at this time, investigators report that the information provided by Mr. McClure appears credible and is consistent with previously known details surrounding Grissim’s disappearance, particularly those supporting the belief that her remains may be in the Dole Valley area. Grissim was reported missing in December 1971. In the Spring of 1972, her high school identification was found on the side of the road in Dole Valley, approximately 1.5 miles north of where two murder victims’ remains were discovered in 1974. Those two victims were later identified as Carol Valenzuela and Martha Morrison. Warren Leslie Forrest was convicted of Morrison’s murder in February 2023.

Mr. McClure is not suspected of any involvement in Grissim’s disappearance or any related crime.

As a result of the new information and McClure’s cooperation, the Cold Case Team is coordinating with Washington State Search and Rescue and Clark County Search and Rescue to plan an additional search effort in the Dole Valley area. This search will utilize human remains detection dogs—specialized canines trained to locate human remains that may be deeply buried and several decades old. The search operation is pending final logistical planning and resource availability.

Recently, the Seattle Division of the Federal Bureau of Investigation has joined the investigation and is consulting on laboratory and investigative matters.

Further updates will be provided as the investigation progresses. Anyone with information on this case is asked to call the Cold Case Tip Line at 564-397-2036.
