Four women, long believed to be victims of the Green River Killer, are still missing.
Two other women - whose bodies were found after they disappeared in the 1980s - are not on the list of 48 women Gary Leon Ridgway said he killed.
So the families of those six women were denied whatever closure was available at Ridgway's sentencing Thursday, when those who lost loved ones addressed the court about their years of pain, loss, rage and, in some cases, forgiveness.
That's because prosecutors didn't have enough evidence to file a charge in those cases.
Ridgway told detectives he's certain he killed three of those women - Keli McGinness, 18, missing since June 28, 1983; Kase Ann Lee, 16, last seen by her husband Aug. 29, 1982; and Patricia Osborn, 19, last seen on Seattle's Aurora Avenue North on Oct. 20, 1983. But their remains were never found to corroborate his claim.
Mary Marrero knows how their families feel. Her sister, 20-year-old Rebecca Marrero, disappeared Dec. 3, 1982, leaving behind a 2-year-old daughter. She vanished from a motel on Pacific Highway South - a favorite hunting ground of Ridgway's. Her body was never found.
Mary Marrero wishes she'd had the chance to tell Ridgway how much her family hurts.
"We want to bury her where we want her, not where he left her, out in that cold weather, where he left her like a dog," said Marrero, 38. "It would have helped for my mom. She thinks Becky is still alive."
The situation is a little different for Jason Liles, whose 16-year-old sister, Tammie Liles, disappeared from downtown Seattle on June 9, 1983.
Her remains were found three years later in Tualatin, Ore.
"I was 15 when they had to bury her in a baby casket, because we couldn't find all the parts of her body," said Liles, now a 32-year-old New York police officer who was in Seattle for Ridgway's sentencing Thursday.
But her name was not on Ridgway's list.
"You live with this for 20 years, wondering what happened," he said. "I think it would settle a lot better if the guy would say, 'Yeah, I did it.'"
Ridgway remains a suspect in the open cases and could still be charged in some of them, said spokesman John Urquhart with the King County Sheriff's Office.
He's also a suspect in the death of a young woman whose remains were found with Ridgway's help but has not been identified.
