Please help me find this crime TV show

I need to find the name of this TV show and the season and episode. A woman was holding people hostage until she got more information on her son’s wrongful conviction in her mind. The woman’s son killed his sister by pushing her down the stairs, The main point of the interrogation was that there was a 45 minute pause between the interrogation and the confession. They  interviewed the killer in jail who said they were high at the time of the killing. The woman holding the people also had a Killswitch that would detonate just by touching her heart. I believe the son's name was Jacob and the daughters name was Emily. Father also said to Jacob, that it was time to step up for what he had done. The sister had broken her neck, and the mother was part of the DA that wrote the book on bombs I am not confident on the names though. I also remember a character named Danny. 
Specifically focus on the 45 minute pause,, the mother writing the book on bombs, the son admitting he was high at the time of the killing and the mother playing a voicemail for the detective from the daughter Saying that she would get her own dinner. . They were doing the interview with the son in jail, and the specifically said I was so high. She was in so much pain. The father specifically told the son it was time to step up and admit what he did
