Snay won $10m through the Massachusetts state lottery

Daniel Snay's win attracted the attention of the police in Connecticut, where he had lived for many years. They say he never informed them of his move.

He faces up to five years in prison if convicted of failing to notify authorities of his change of address.

His lawyer says when Snay moved, he registered only in the new state.

"If that is incorrect, we'll have to fix it," lawyer Joseph Fabbricotti said. "He wasn't running. He's been living here for four years."

Connecticut police said Snay had not confirmed his address for the Connecticut sex offender registry since 2004.

"We're trying to determine when he moved, why he didn't register with us and whether any charges are warranted," a spokesman said.

'Most dangerous'

Snay paid $20 for his "Billion Dollar Blockbuster" scratch ticket at a suburban convenience store in Massachusetts, where he has lived since 2004.

The 56-year-old was convicted several times of indecent assault and battery in the 1970s and 1980s, with two of the assaults involving a child under the age of 14.

But he is not banned from gambling.

He is classified in Massachusetts as a Level 3 offender, which puts him in the category of most dangerous or most likely to reoffend.

It is the second time in recent months that a convicted offender has won the Massachusetts lottery.

In January, a judge allowed a bank robber to keep a $1m lottery prize even though his probation terms forbade him from gambling.
