Hi Dp, you should really check with the local JC police and sheriffs departments for this data. They will have the most accurate information. A realtor can't really give you a fully "legal" opinion on this issue for a variety of reasons related to real estate laws and professional liability.
If I can help you out give me a call at 201-486-2974.
The best source for this information is the local police department or county sheriff's department. they have access to the most current and accurate information and are generally very will in to be helpful.
