PORTLAND, Ore. (KOIN) — Warren Forrest, a convicted killer considered one of the worst killers to prey on women in the Vancouver and Portland area, was once again up for parole on Tuesday.

Forrest, now 68, has been behind bars on a murder charge since 1978 and is accused of attacking 8 women, including one whose body has never been found.

Before his murder conviction, he pleaded not guilty by reason of insanity to the abduction and brutal attack on a 20-year-old woman, who he abducted from Portland and left for dead at Lacamas Lake Park near Camas on October 1, 1974.

After several years at the state hospital, Forrest was about to be set free when Clark County prosecutors charged him in the death of 20-year-old Krista Blake. Her body was found on July 11, 1976 in a shallow grave 200 yards from where he admitted attacking 15-year-old Norma Countryman. Blake was last seen getting into a blue van in Vancouver exactly two years earlier.

Forrest was convicted in 1979 and has been in prison ever since. In a 2014 parole hearing, Forrest admitted what he did.

“I attacked the individual. While forcing the victim to undress, there was a struggle and during the struggle I choked the victim to death,” he said.

He was denied parole in 2014 and this parole hearing was his regularly scheduled hearing.

While locked up, Forrest married his prison nurse. Now in her 80s, Hilda Forrest lives in Walla Walla, Washington and KOIN 6 News tried to speak with her through her front door.

Just last month, Clark County investigators met with Forrest and told him they’re working to prove he killed 5 other young women: Carol Valenzuela, Martha Morrison, Gloria Knutson, Barbara Ann Derry and Jamie Grissim.

The parole board asked Forrest about the other victims but he would only say he feels sorrow for those families, and that talk of other crimes is “not factually” accurate.

Forrest told the parole board the crimes he committed were because he allowed stress in his life from working 2 jobs, going to school and being a father. He said, “The only option I had was to distract myself, and I chose to live out those violent fantasies.”

The parole board has 30 days to decide if all the sex offender treatment and other prison programs have rehabilitated him enough to be set free.

By the sound of their questions, that doesn’t seem likely.
