That is such a hard question to answer! The best advice I can give you is to contact the police department. They can answer all your questions regarding the neighborhood.
I looked in the MLS at the house you mentioned and the listing expired yesterday. Unfortunately, it can take a couple of days for the information to be updated on all the other websites. If you are currently working with an agent, your agent should be able to find out if the seller is still interested in selling the home. If you are not working with an agent, I will be more than happy to help you. You can call me and we can discuss the options. (860) 705-4433.
