Sharon Clizer, the mother of one of his victims, is working to create a new law that further protects victims.
"The reason we reached out to our representatives is this may not help this case but we're hoping to save other victims in the future," said Clizer.
Hoisington, 61, is set for release in mid-June after state psychologists reported he's no longer deemed a sexually violent predator under the specifications listed by the state. He served time in Idaho and Washington for brutally raping women.
"Why are these people allowed, when we know they are perpetrators and we're going to let them out on the street," said Clizer.
Clizer says they'd like to help change how psychologists test and analyze the prisoners before they're allowed for release. She'd also like to see more rights for victims of sexual assault.
"They said it's so hard and so expensive but I think we have enough people in our community alone who'd be willing to jump on board," said Clizer.
Clizer said she's working hand-in-hand with Washington State 9th District Representative Susan Fagan to make it harder for sexual offenders to be released.
"It'll probably be slow, but it's just not common sense," said Clizer. "It doesn't make any sense at all."
Hoisington's release is set for June 12th. Stay with KLEW News as we follow Clizer's efforts to create a new law.
