Fight night at the trailer: Homeless sex offenders get into scuffle

A man living at the Suffolk County homeless sex offender trailer in the county jail parking lot in Riverside reported last Tuesday that he was punched in the face by a fellow trailer resident with whom he’d had an argument, according to Southampton Town police.

The suspect in this case is listed by police as Lucas Rivera, 50, who has lived at the trailer since at least 2008 and has been arrested several times over the years, including once in 2008 for urinating on Riverhead police headquarters, another time for causing a disturbance at the Riverhead 7-Eleven and once last year for failing to personally verify his address with local law enforcement every 90 days, as required by law, according to police.

According to the state registry, Mr. Rivera is considered a Level 3, or high risk, sex offender. He was convicted of third-degree attempted sodomy in 2002 and spent nine months in jail, according to the registry.

The victim, Phillip Riley, 50, sustained redness and swelling on his face, police said. He is listed on the state registry as a Level 2, or medium risk, sex offender. He was convicted in 2008 of second-degree sexual conduct against an 8-year-old child and spent three years in state prison, according to the registry.
