Charisma

S6 E7: A 12 and a half year-old girl, Melanie (Holliston Coleman), arrives at the hospital, pregnant, and won't give anyone information about herself. Benson (Mariska Hargitay) persuades her to write down her address, and gets the name of the baby's father - Abraham (Jeff Kober), Melanie's husband. When Benson goes to the address, she sees numerous children inside and a very strange and dangerous looking Abraham at the door. He slams the door on the police - then they hear shots fired. All of the children in the house are found dead and Abraham has escaped.
