A Newport man accused of photographing a young boy in the bathroom of a Walmart store in Palmyra is expected to accept a plea deal Monday in Bangor District Court, according to the Penobscot County district attorney.

District Attorney R. Christopher Almy said that if Marc Alberi, 46, pleads guilty to the three charges pending against him in the case, prosecutors will recommend a three-year sentence.

Alberi was arrested Sept. 8 after allegedly using his cellphone to take pictures and video of an 11-year-old boy using the urinal in the Walmart restroom. The boy notified store security officials and a Walmart manager used surveillance tapes to identify Alberi and report the crime to police.

He is charged with possession of sexually explicit material depicting a child under 12, violation of privacy and prohibited contact with children under the age of 14.

Alberi was released on $2,500 cash bail in September. His attorney, Steve Smith, could not be reached for comment Thursday.

Alberi is a registered sex offender with five convictions of unlawful sexual contact and three convictions of gross sexual assault. All eight convictions stem from a 1998 case in Oxford County.

He is scheduled to appear at 1 p.m. Monday in court at the Penobscot Judicial Center.
