You have a couple of options when it comes to the crime rate in an area. One is to look at it through Trulia. There information is pretty up to date and accurate. The one that I recommend is www.cmpd.org. Once you go on the website you can click on the For Your Safety along the top and there is a link to crime mapping. Put in the address and it will give you the stats you are most likely looking for.
That is the most up to date site and I found the best site for that type of information.
