TROY — A retired Albany police DARE officer will serve six years in prison for sexually abusing a teenage boy.

Paul Pierce, 59, of East Greenbush was sentenced Friday by Rensselaer County Judge Robert Jacon, who convicted the former officer after a three-day bench trial in April.

The teen victim's father said in court that his son "suffered sexual abuse from the time he was 15 until he was 17" as a result of interacting with Pierce, a man he trusted.

Pierce will serve four years for one count of third-degree criminal sex act and two years for an additional count of third-degree criminal sex act, both felony charges. The sentences will be served consecutively for a total of six years. A sentencing for child endangerment will run concurrent with the other charges.

Pierce will also serve 10 years of post-release supervision. The judge also signed an order of protection forbidding Pierce from having contact with the victim or his sister until 2036.

"I offer my sincere apologies," Pierce said in court.

Asked for comment afterward, Pierce walked away in silence.

Outside the courtroom, the victim's father said he was upset that Pierce did not apologize for what he did to the teen and that the sentence was "what he deserved."

District Attorney Richard McNally said Pierce had not accepted responsibility for his actions.

McNally said the case was "very, very difficult" and praised the prosecutor who handled the case, Assistant District Attorney Michelle Poole.

Pierce will remain free until July 5, the day he is scheduled to be sentenced in Warren County Court for similar charges involving the boy and his sister. Those attacks took place in Chestertown. Pierce will then be sentenced July 20 in Albany County Court for abusing the boy in an Albany home.

The counties' prosecutors have agreed that Pierce will serve the same sentence concurrently as he received in Rensselaer County.

"This case is tough," said Andrew Safranko, Pierce's attorney. "There are no winners."
