PRESQUE ISLE, Maine — A 36-year-old man who is a lifetime registrant on the state’s sex offender registry was arrested for the second time in less than two years on Thursday after allegedly changing residences and failing to let police know in a timely manner.

State law requires people who are on the sex offender registry to notify local police within 24 hours of relocating to a new city. It is a felony to violate the law.

Presque Isle police Detective Bill Scull said Friday that Marco Cullins first failed to comply with that law in 2013.

Cullins had been convicted in California of distribution of obscene material and possession of obscene material. It is not clear when he moved to Maine, and more information about those violations and when they occurred was not available from the online registry Friday.

After Cullins was found guilty of failure to comply with the Maine sex offender registry act in 2013, he was fined $300.

Most recently, Cullins moved to Presque Isle from Bridgewater and again did not let the police know, according to Scull.

“We have a number of sex offenders that we remain vigilant in keeping track of,” he said. “But at the same time, they know they are expected to check in like this if they move.”

Scull said Cullins was arrested on the most recent charge and posted his own bail.

Presque Isle Police Chief Matt Irwin stressed his department’s continued vigilance.

“The issue of sex offender registration has been around for quite some time now and the requirements imposed upon registrants are made very clear to them,” said Chief Matt Irwin. “Sex offenders should understand, we take these matters very seriously.”
