not change what happened. >> february 29, 2016, almost four years since annie's murder and darwin christopher bagshaw's trial was just a week away. he had refused to talk to police and pleaded not guilty. >> we were preparing for trial the following week and i got a phone call that chris' attorney scheduled a hearing that day. >> jaclyn, now a sergeant with the utah state police ran down to court and barely made it in time. when she got there, she saw chris standing before the judge. >> the case is set for a change of plea hearing today. are we going forward with that? >> yes. >> there was no deal offered, just a change of heart. >> are you pleading guilty to the charge because you're guilty of it? >> yes, your honor. >> chris' attorney said chris wanted to take responsibility for what he had done. >> all right. as to count one, murder or first degree felony, how do you plead?
