He has his baby in his hands. He has a large knife to the baby's throat. Put the knife down. Hey, put the knife down, man. Come here. You got a beautiful kid right there, man. Shoot me then. No. Hey, we're not doing that, bro. No. No. When he realized that there was no way out, he set his bedroom on fire and hid in the bathroom. >> The smoke is building. We can see the flames growing. We are losing our opportunities to help and save this child. Firefighters had to cut through the bathroom wall to save the baby, who might have been suffocating from smoke. We don't know what this assailant is. We don't know if he's waiting for us with a weapon. Here is one suspect in here. Baby, baby, baby, baby, baby. Baby wasn't breathing.
