BUT, he claims he accidentally discharged the gun, it caromed off of a linoleum-covered concrete floor and then struck her. It all occurred in a very small kitchen.

The round deflected or bounced up to at least 5 feet in height, assuming she is at least 5 feet tall, to enter her skull within 5 to 10 feet? That is some ricochet.

1. What is the muzzle velocity of the round?
2. What is the velocity of the round at 10 feet?

Usually around ~3100 to 3250 fps for a 55 grain .223 bullet, and depending on the length of the the barrel. At 10 ft, about the same as muzzle velocity.

"...That is some ricochet...."

I know, right? But a direct shot at 10 feet makes less sense, at least fitting the evidence. C
