VANCOUVER, Wash. – Mary Nosack says she was upset when she learned that a “very dangerous serial rapist” would be released from prison early.

That convicted rapist is Nosack’s younger brother, William, who was convicted of sexual abuse in 1990, 1992 and 1998.

“We counted up 31 people he had attacked, molested or raped,” Mary Nosack told KOIN. “Some are family members, a lot were old girlfriends, people he knew and most recently he was just more opportunistic.”

Nosack says she is concerned that he will attack someone else.

“Absolutely without question,” she told KOIN. “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 supposed to be eligible for release on July 22, 2016, but the Oregon Department of Corrections re-calculated his sentence.

He is to be released on April 12.

Officials say he will be forced to wear an ankle monitor and will undergo a threat assessment.

However, Nosack doesn’t know if that is enough.

“I want people to know that he is dangerous,” she said. “Don’t trust him, don’t allow him to be anywhere near yourself or your children.”
