VANCOUVER, Wash. (KOIN) — Mary Nosack was shocked to learn a “very dangerous serial rapist” will be released from prison on Thursday. She’s also outraged she and her family only got 2 days notice about his release.
The rapist is Mary Nosack’s younger brother, William Nosack. She’s most concerned “that he will hurt another family member or someone else.”
William Nosack, 58, was first convicted of sexual abuse in 1990. He was again convicted in 1992 and 1998. In 2006, he was convicted of being a prison inmate in possession of a weapon.

Mary Nosack told KOIN 6 News she and her mother had a long talk about William. “We counted up 31 people he had attacked, molested or raped. Some are family members, a lot were old girlfriends, people he knew and most recently he was just more opportunistic.”
One of his victims, she said, was a 6-year-old.
“It has affected her life in ways that no one will understand and now she stands in fear that he’s getting out and what might happen to her again.”
Her biggest concern is that he will attack someone else.

“Absolutely without question,” she said. “It has been his pattern of behavior to go from one to the next and with each attack it gets more and more violent.”
William Nosack was convicted in 1998 after he attacked someone across the street from his halfway house in Marion County, she said.

“I want people to know that he is dangerous,” Mary Nosack said. “Don’t trust him, don’t allow him to be anywhere near yourself or your children.”
She was expecting an earlier notification if he was going to be released from prison. But since the family only got 2 days notice, she said, “We’re doing our due dilligence and part of meeting with you is to get the word out about this very dangerous, serial rapist.”
William Nosack was to be eligible for release on July 22, 2016. But the Oregon Department of Corrections re-calculated his sentence and determined “is to be released Thursday, April 14, 2016,” according to the notification letter.Department of Corrections statement
In a statement to KOIN 6 News, Oregon Department of Corrections Communications Manager Betty Bernt said he was deemed eligible for release during a routine review.
“Based on this review, Mr. Nosack was deemed eligible for earned time sentence reduction (pursuant to the Oregon Administrative Rule on Prison Term Modification) after the service of his Measure 11 minimum sentences. …”
Bernt added, “In the event of an immediate release, every effort is made to ensure that a victim who has requested release notification is contacted as soon as possible.” They do admit his file should have been reviewed sooner.
When he is released, he will be living at the transition center at the Marion County Jail. He will wear an ankle bracelet with GPS tracking and will undergo a threat assessment. Marion County officials told KOIN 6 News when he is released into the community, residents will be notified.
“Because this is my brother I would really want no harm for him, but he cannot be in society,” Mary Nosack said. “We know that, we who have lived with this for over 30 years.”
“The only thing we can do is warn people.”
