BOSTON (AP) – A defrocked Catholic priest who already served three years in a New Hampshire prison for sexually abusing a child pleaded guilty Friday to sexually abusing five other boys, and was sentenced to eight to 11 years in prison.

Robert Burns, 56, was indicted in April on six counts of raping of a child under 16, and seven counts of indecent assault and battery on a child under 14. He pleaded guilty to all 13 counts.

During the hearing, Burns apologized to his victims – who were all boys age 10 and under when the abuse began – to the people in the two Boston parishes he served and his fellow priests.

“I can’t undue the harm that I’ve done, but I am determined to live the rest of my life with integrity,” he said. “I am deeply, profoundly sorry.”

The abuse took place from the mid-1980s to the early 1990s, while Burns was a priest at St. Thomas Aquinas Church in the Jamaica Plain section of Boston and at St. Mary’s in the Charlestown neighborhood.

Four of Burns’ victims gave emotional statements in court before he was sentenced, describing the damage the sexual abuse had caused in their lives.

One man, who is now 28, said Burns began abusing him when he was 10. He said Burns befriended his large Irish-Catholic family and showered him with praise and gifts.

The man repeatedly wiped away tears as he described how Burns went from kissing him on the forehead and giving him huge bear hugs to molesting him repeatedly.

“I was so confused about what was going on that I didn’t say anything,” he said. “Who was going to believe a kid?”

The man said he became a drug addict while still a teenager, and was admitted three different times to psychiatric wards for attempting suicide.

“Bob Burns, now it’s time to take your turn in hell on earth,” he said.

Prosecutor David Deakin had asked for a sentence of 12-15 years, while Burns’ lawyer Timothy P. O’Neill asked for five to eight years.

Suffolk Superior Court Judge Margot Botsford said she had to weigh the severity and length of the abuse with what she said was Burns’ remorse and efforts to rehabilitate himself.

“There can be no question that the defendant’s repeated sexual abuse of these boys … has permanently and profoundly injured each of them,” she said.

Burns was taken away immediately to begin serving his sentence, which will be followed by 10 years probation.

The archdiocese investigated one family’s claim of sexual abuse by Burns in 1991, and eventually dismissed him from his parish assignment.

Burns then moved to New Hampshire, where he was arrested in 1995 and pleaded guilty to molesting a child while working outside the priesthood. The church defrocked him after that conviction.

District Attorney Daniel Conley said at the time of Burns’ indictment that neither that family nor the archdiocese reported the abuse to law enforcement. Conley said prosecutors learned of the allegation in 2002, when the archdiocese agreed to turn over any such allegations to authorities.
