numbers of suicides and homicides solved

I've heard that -- there are twice as many suicide deaths as homicides.

One half of all homicides are not solved.

I don't know how the statistics for accidental deaths fit in, if you do, please comment.
But since I consider accidental deaths by car or by gun as violent... Is there a particular statistical category for violent deaths of different kinds - with the numbers?

The numbers of returning vets from the middle-east oil wars who commit suicide is astounding, and very sad. The numbers of their wives killed is also astounding.
