Last year somebody sued the landlord of an apartment complex for failure to maintain safe premises -- because she was struck by a stray bullet fired by an unknown person during New Year's revels.
It must have been a fairly large rifle bullet to penetrate the roof of a church building and still retain enough velocity to kill this poor little kid.
7.62x39 FMJ would be my bet, combined with a flimsy church roof. No way a handgun projectile would do that.
Not just there it happens a lot here too. We are in SE Ohio and last night at midnight I heard them going off all over. I just said to Dh ;ast night that it would be awful to be sitting in your livingroom and be killed by a stray bullet.
