My 8 year old step son is tearing our family apart with his behavior. It is getting so bad that my 10 year old daughter is afraid of him. He has been stealing anything he can get his hands on at home, school, and at our families homes. He has taken money, medicine, toys, candy, gum, etc. He has been given time out, tv time and video games have been taken away, kept home from fun family outings. We have caught him red handed and he makes out outrageious stories ranging from it wasn't him to his father told him too etc. He has been lying about school work, hiding stuff when he is supposed to clean his room. The more he gets caught and punished the more he does it and harder he tries not to get caught. He threatens his older sister and two toddler brothers so they won't tell on him. He has been outraged when he gets caught and threatens to burn down our house, kill his sister in her sleep, etc.
