If you shoot someone, you will be charged with attempted murder. Even if you don't aim for the head or heart, the victim could well bleed to death.
The father got probation. 5 years I believe, it was not long. It was a plea bargain. The molester's family was upset, but the prosecutor said if it had went to trial he doubted he could find a jury that would convict the father. So he offered a pretty light deal and it was accepted.
