You should ask local law enforcement if you want to know the answer to that question. The Real Estate Agent who has the listing has a clause in his/her listing agreement prohibiting the person from mentioning anything that could psychologically stigmatize the property, and other agents on here would do well to steer clear of the question, too, as we do not have any duty to find out this info for a prospective buyer.
Besides, local law enforcement can give you factual data, while a general member of the public, like a real estate agent, probably would only know the rumors surrounding any possible information. Good luck!... more
