Where can I find murder statistics broken down by demographics (specifically age)?

Question

I'm trying to determine how many children were killed in the city of Washington, D.C. last year (or whatever year). Is there any agency or place that would collect or breakdown this statistic?

Answer 1

Here is a homicide trends web page from the Justice department. And an Fbi report that is more current. The first has links to other sources if you browse a bit.
