If you want to make it even more complicated use a smaller gun of a larger caliber but use some sort or cartridge holder to fire a smaller diameter bullet in a larger diameter barrel but keep the range short as it might have an unusually low velocity for that type of weapon… coroners report might make it look as if the bullet must have passed through something before striking the person suggesting person was moved. Even finding the weapon recently fired on the woman it is the wrong caliber and ballistics would not match as smaller ammo might not even touch the sides of the inner barrel.
