A parole board is again considering whether a convicted killer suspected of slaying several Clark County women in the 1970s will remain in prison.Warren L. Forrest, 64, of Battle Ground is eligible for parole on March 16. The Washington Indeterminate Sentence Review Board has until that date to decide whether he will be paroled.As part of that process, the board’s four members on Monday heard from one of Forrest’s surviving victims and family members of other girls he’s suspected of killing. All are opposed to Forrest’s release or a less-restrictive placement.“There is no way a guy like that deserves to even think about leaving prison,” said Starr Lara, sister of one of the victims Forrest is suspected of killing. She spoke before the parole board on Monday.Her sister, Jamie Grissim, was a 16-year-old student at Fort Vancouver High School when she disappeared Dec. 7, 1971. She has never been found and hers remains the oldest missing person’s case in Clark County, according to the sheriff’s office.
