Syracuse (WSYR-TV) – A former City of Syracuse Department of Public Works employee with a litany of arrests for sex crimes involving underage boys is once again facing charges.

Mark Carrigan, 46, of Syracuse, was arrested Tuesday on charges of criminal sex act in the second degree and failing to register an internet identifier, both felonies, as well as forcible touching, a misdemeanor.

“Mr. Carrigan is somebody who continually thumbs his nose at the system and breaks all those rules. Those rules are put in place to keep people safe, to keep children safe. Mr. Carrigan continually breaks those rules,” said Sergeant Tom Connellan with the Syracuse Police Department.

Police say Carrigan’s most recent victim is a 14-year-old boy he met in September 2012.

After their first encounter, police say Carrigan began picking the boy up at a school bus stop and other locations including fast food restaurants.

Police say the man gave the boy fast food routinely and also gave him a small amount of cash. Connellan says that Carrigan has made a routine of the gifts.

“He'll shower these kids with gifts that kids would like, take them for fast food, give them money and shower them with things and then he turns around and tells them that he expects something in return for it,” said Connellan.

Carrigan is facing his most recent charges after he allegedly performed sex acts on the boy in a relative’s home.

A school employee reported Carrigan to police when he recognized him as a sex offender while driving the boy to school.

Carrigan was arrested for probation violation at the time and police began their most recent investigation.

He was arrested upon his release from the Jamesville Correctional Facility for the probation violation on Tuesday.

He is now being held in the Onondaga County Justice Center pending arraignment.

“We're hopeful that we're going to be able to keep him incarcerated for a very long time after this,” said Connellan.

Carrigan has been arrested on 16 occasions on 40 different charges.

Of those charges, 16 were felonies and 22 were misdemeanors, along with two other charges.

Out of 16 felonies, 3 resulted in convictions. 12 of the 22 misdemeanor charges resulted in convictions.

“He is a level 3 (sex offender). He is the highest level that you can be and he's considered a dangerous person. He should not be around children and he's not allowed to be around children. But, he continually breaks those rules,” Connellan said.

Police say they strongly believe Carrigan has other victims, a belief that Linda Cleary, the Executive Director with the McMahon/Ryan Child Advocacy Center echoes.

“My first thought was, we know how many children have come forward, how many have not,” Cleary said. “It's very few children that are going to come forward and say it, so every time you know they've done it with one or two children, chances are it might be 10, 20, or 30 children that they've been doing it with.”

Anyone who can contribute to their investigation should call (315) 435-3016.
