Snay was convicted of a series of assaults in the 1970s and 1980s, including two counts of indecent assault and battery on a child under 14 and two assaults on a person over 14.
Snay is classified in Massachusetts as a Level 3 sex offender, who are those the state considers the most dangerous and most likely to re-offend.
Connecticut officials are considering charging Snay because he allegedly failed to notify police in 2004 that he was moving to Massachusetts. Snay is a truck driver for a boat dealership in Mendon.
