A Pennsylvania college graduate has been sentenced to more than 13 years in prison for sexually assaulting two of his fraternity brothers in their sleep.

Robert Convery Jr, 23, of Williamstown, New Jersey, was convicted last year of three counts each of involuntary deviate sexual intercourse and sexual assault targeting two Albright College students, one of whom was attacked on two separate occasions.

Each incident occurred at the Pi Kappa Phi fraternity house in the 1600 block of Pike Street in Reading, Pennsylvania, after the victims fell asleep following parties where alcohol was being consumed.

On Wednesday, Judge Paul M. Yatron sentenced Convery to 13-and-a-half to 30 years in prison, reported the Reading Eagle.

As part of his punishment, Convery will also be required to register as a sex offender for the rest of his life.

When given a chance to speak at his sentencing, Convery, who graduated in May 2015 and said that he had aspired to become an attorney, tearfully admitted that he made a 'mistake.'

'I'm sorry. I'm going to take the consequences,' the defendant told the court. 'I want to have a future after this. I'm a good person, I really am.'

Prosecutors said during Convery's two-day trial in June that he sexually assaulted one fellow member of the Pi Kappa Phi fraternity in December 2013 and again in November 2014. The second victim was attacked in February 2015.

The man who was assaulted twice testified that he got drunk during a Christmas party in December 2013 and fell asleep on a coach at the Reading frat house. When he woke up, he found his pants down and Convery assaulting him.

The other victim said from the stand that in February 2015, he was asleep in his bed after a night of drinking when he was awakened by the defendant assaulting him.

On Wednesday, Judge Yatron had a prosecutor read aloud a four-page letter from the victim who was assaulted twice, in which the man, now aged 23, said that he was willing to forgive Convery after the first incident, but when he assaulted him a second time, he felt that he could not stay silent.

The man also wrote that he does not know if he will ever be able to forgive Convery.

‘One can only hear the words "I'm sorry" so many times before it loses its meaning,’ the statement read. ‘I believe if there is even an ounce of an apology, it's only a result of being caught.’

A half-dozen supporters, including Robert Convery's mother, took the stand to speak in his defense, describing the college graduate as a caring and respectful young man who has had a positive influence on those around him.

The judge said that while he believes that Convery has many redeeming qualities, the severity of his crimes cannot be overlooked.
