>> according to her testimony, smith was in the house with the victims as part of the fake date and she sent text messages with what was inside. bell text messages with descriptions of the items in the house and who was inside. prosecutors say bell responded with these text message, indicating his intention to kill victims. >> when somebody tell you they about to do something like that you don't really think oh are they about to go -- i didn't believe that that's what the outcome was going to be that night. the main thing that makes me feel guilty and i regret is not calling the police. because i could have prevented this all. and i know that i'm guilty for not putting a stop to it. and also i did lie and cover for him. i should never have covered in the first place. i feel like i made the right choice by testifying. because at the end of the day, it all boils down to my son.
