Then, as always, do your own research -- pop the address into google, with descriptive text that captures your concerns and see what comes up. You could also try the local police. For any aspect of a purchase that matters greatly to you, it is always good to do your own research.

If you can look beyond that circumstance sounds to me like an opportunity to purchase that home at a discounted rate. I say this because I am aware of a home in Manaquan, NJ wherein a murder took place that sold at below market value. It was torn down and a new property rebuilt, but that type of stigma MIGHT provide you with leverage to purchase the property at below market value.
