WOODBURY - Sex offenders in five counties across New York state, including Nassau, have already challenged their local residency restriction laws in court and won. Now, an offender in Suffolk seems to be one step closer to winning his case, too.Duane Moore is a Level 3 registered sex offender, who served 19 years in prison after pleading guilty to two separate rape charges back in 1982. His lawyer says finding a place to live once he was out of jail was so challenging that he's now suing Suffolk County.Suffolk's residency restriction laws dictate where registered sex offenders can and can't live, and how far away from schools, day care centers and playgrounds they need to be.Laura Ahearn, of Parents for Megan's Law, says she's worried that Moore will win in court. She says she wants to see the state pass residency restriction laws based on county populations.
