Mattapoisett police notify public of Level 3 sex offender living in town
The department said state law requires it to actively notify the public of a Level 3 offender, and its post does not say he is wanted or accused of a new crime.
MATTAPOISETT Mattapoisett police notified the public Monday that a man the state classifies as a Level 3 sex offender lives in town, posting the state registry flyer with his name and photo on the department's Facebook page.
The flyer, from the Massachusetts Sex Offender Registry Board, identifies him as Kenneth McCarthy, 56, and lists his home on Marion Road in Mattapoisett.
The department said the board has determined that he presents "a high risk of re-offense and a high degree of dangerousness to the public," and that state law, Chapter 6, Section 178K(2)(c), of the Massachusetts General Laws, requires police to actively notify the public and organizations likely to encounter a Level 3 offender. The department posted the notice Monday morning.
What the flyer lists
- One conviction or adjudication for indecent assault and battery on a child under 14, dated June 20, 2013.
- Two convictions or adjudications for open and gross lewdness and lascivious behavior, dated June 20, 2013, and Dec. 19, 2024.
Using the registry
The post does not say he is wanted or accused of a new crime, and the flyer warns that registry information may not be used to commit a crime against an offender or to harass or illegally discriminate against one, and that doing so is punishable by up to 2 1/2 years in a house of correction, a fine of up to $1,000 or both.
The flyer tells anyone who believes a listing is inaccurate to contact local police or the Sex Offender Registry Board at 978-740-6503, 8:45 a.m. to 5 p.m. weekdays. Mattapoisett police can be reached at 508-758-4141.
