Mommy Daddy, I coming. >> What drugs, though? >> Mommy Daddy, I coming. >> If you can't handle being a parent, don't have kids. >> 5 days have passed since that terrifying night. Now, investigator Anthony from the Department of Children and Families arrives for a follow-up. They are here to see if the home is truly safe. >> My name is Anthony from the Department of Children and Families. I'm the investigator. I'm here to tell you why I'm coming tonight. >> Yeah. >> All right. How are you doing? I'm just here to talk to you regarding what happened at this place. Is there anything I should know before I come in? >> Yeah. >> All right. >> As the investigation deepens, Caitlyn tries to maintain a calm exterior. However, the investigator starts questioning her about the real reason she was so heavily asleep that night. The focus shifts to illegal substances. >> Are you taking Xanax or anything like that or any kind of medications? >> All right. Taking Xanax. >> Do you have a prescription for that? >> No, sir. >> You don't? Okay. >> The confession is the final blow. Caitlyn admits to taking Xanax without a prescription. Combined with alcohol, it created a deadly environment for a child. Law enforcement decides that enough is enough. >> You're under arrest. Stand up. Put your hands up. Put your hands behind your back. Do you want your phone or your ID with you? >> Yes, please. >> You can take your phone down there and um if correction staff allow it, they sometimes allow you to take your phone or take contacts out of your phone, okay? >> Caitlyn Ryals and Derek Sobeck are both taken into custody. Paisley is placed in safe care, away from the parents who chose substances over her safety. A dark chapter ends with a chance for a new beginning.
