Ever since living in New York I' am always reading the Times and The New York Post for all my crazy happy sad news. Since 2003 there have been approximately 3 thousand murders in the five boroughs. I personally though it was going to be more, but they can tell you all sorts of information about these incidents. Like what what used to commit the crime, the time of day, the motive, and even the sex of the person.
The Times have an interactive map that is pretty tight. Check it
