SMETHPORT — A Shinglehouse man who is accused of sexually assaulting a teen will serve 10-20 years in state prison.

Jason M. Milliken, 43, was sentenced Thursday in McKean County Court before President Judge John Pavlock.

Milliken pleaded guilty Jan. 21 to charges of involuntary deviate sexual intercourse of a person less than 16 years old, a first-degree felony; recklessly endangering another person, a second-degree misdemeanor; and incest of a minor, a second-degree felony.

Milliken has credit for 253 days of time served. In addition to the prison term, he will serve three years of consecutive probation, and he was ordered to pay $2,845.41 in restitution. He must register as a sex offender for his lifetime.

His husband, Aaron D. Waters-Milliken, is serving 10-20 years in prison also for similar allegations that happened at the same time.

Prior to ordering the sentence, Pavlock said that while this is a substantial sentence for Jason Milliken, Milliken “sentenced the victim for life,” as the boy will still have to deal with any worry, memories or trust issues related to the assault.

District Attorney Stephanie Vettenburg-Shaffer said Milliken violated his duties to the boy “in the worst way possible, not only by sexually assaulting him but also exposing him to disease.”

Milliken pleaded guilty on Sept. 5 to allegations that he and his spouse had a 14-year-old spend the night at their residence in Shinglehouse. They were drinking alcohol, then all three went to sleep in the same bed with the 14-year-old sleeping between the two adult men.

Jason Milliken had sexual contact with the teen, which exposed the teen to a communicable disease; the teen had to take medication to protect himself from getting the illness and must undergo testing for several years, according to the information to which he entered his plea.
