I DO HOPE HE DID NOT MAKE TOO MUCH OF A MESS INSIDE THE HOUSE.
That was my first thought too.........
Sounds like the perp made it outside before he bled out, which was darned considerate if you ask me. A stain here and there isn't too bad but getting a whole pool of blood out of the carpet is sort of expensive.
Uh...or so I've been told.
Get a claim against the perp's estate (as if he has any) for the cost of the cleanup.
