Psycho Killer
You go back for your dad to find that he is alive and well, he covered himself in others guts to make it look like he was already killed so no-one else would try to kill him. You both run and dont stop running until you get to the police station, they recognize you immediately, they ask what happened this time, before you can talk your dad confesses everything he has done wrong and says he needs help. They take him to rehab and release a statement saying "Drunk dad admits wrongdoing for his daughter" you live with your grandparents until he gets out, when he came out he was a new man, a better man. He got rid of all his fake military and MMA stuff, the police found the children and got them the mental help they needed. Everything has been grate since this except for one thing... you sometimes find sheep masks in your dads closet.
