His mother is an alcoholic but she managed to control alcoholism with the help of Pit Bull dog Lilly. Unfortunately she went on a walk along with Lilly and fell unconscious on train tracks. Lilly saw the train coming and she did what an intelligent, powerful and most loyal dog will do. She managed to pull officer’s mom of the track but during all the struggle she didn’t have much time for herself to escape and got hit by the train.
