And wow you have no sympathy do you instead of saying sorry for my loss you talk about who ever living until 60-65 and my dad took a bullet for my mom he died when i was 9
If he was shot with a .22 at a closer ranger, he may have passed in instantly. I doubt he was shot with an assault rifle or sniper rifles. It had to have been a pistol. Which does not go through two people, unless it was a .357 or a .44
At a further distance, bullets drop into midsections, or legs. Depending on the distance, the bullet may slow down, resulting in a drop, and depending on the mass of her father, would depend where the bullet went. Good job for assumptions.
