A Tamaqua man serving 20 years in state prison for sex crimes against children will have to register for the rest of his life as a sex offender.

But the state Sex Offenders Assessment Board has determined that Harold Trevorah, 71, is not a sexually violent predator.Judge John E. Domalakes on Tuesday accepted the board's determination. The Megan's law requirements would become effective upon Trevorah's release from prison. He's being held at the state correctional Institution at Camp Hill, Cumberland County.Trevorah on Sept. 23 pleaded to aggravated indecent assault of a child, and two counts of indecent sexual assault of a child and corruption of minors.His plea was "nolo contendere," meaning he does not admit to the facts as presented, but admitted prosecutors would be able to prove them in court beyond a reasonable doubt.Charges of indecent sexual assault by forcible compulsion, aggravated indecent assault by forcible compulsion, aggravated indecent assault of a person less than 13 years old, indecent assault of a person less than 13 years old, endangering the welfare of children, and indecent assault by forcible compulsion were dismissed during plea negotiations.Domalakes sentenced Trevorah to eight to 20 years in state prison."At your age, a 20-year sentence could be a life sentence," Domalakes said at the time.Trevorah, confined to a wheelchair since a stroke, was represented by Gary Marchalk of Tamaqua, who told the judge Trevorah had signed an admission soon after being charged.Trevorah assaulted the girls, who are two months apart in age, throughout 2010, when they were about 7 years old.The assaults came to light in September 2014 when one of the girls, then 11, suffered an emotional breakdown from the burden of carrying the secret, and disclosed what happened.After an investigation, Tamaqua Cpl. Henry Woods filed the charges.According to court documents, neither told anyone about the touching because Trevorah had told them it "was their little secret."Woods spoke to Trevorah, who said, "What I did was wrong and I am going to take responsibility for my actions," according to the documents.
