“I’m having a little trouble buying this story.”
Maybe it was a thatch roof. I can’t believe that terminal velocity of a bullet falling would allow any but the largest, like .50 cal from a .50BMG to go through any but the flimsiest of roofs.
I could be wrong.
It could have been short range direct fire, then a change in direction upon hitting the roof or a truss.
There are dozens of documented cases of falling bullets kiling and injuring. I had a hole punched through the hood of my car from a falling bullet.
