Have a great day,

Your best source for criminal activity in an area is your local police department. They should be able to tell you about the number of calls and exactly what type of calls are taking place in the subject area. Also have you checked with the local City Council to see if these empty delapidated buildings meet City Codes? Many Cities have codes on their books that set strict guidelines as to what condition property owners must maintain their proprty at. That could be a method to go after these property owners to at least maintain their properties. Good luck!
