It is possible that she waves a trial?
She could. She could plead guilty and waive her right to a trial.
If the Prosecutor is asking for the DP - he/she will probably most likely negotiate taking the DP off the table for a guilty plea. The negotiations will depend heavily on what the prosecutor is willing to offer as far as sentence goes and if the perp will accept. I.e., The perp can say - I'll plead guilty if you take DP away and don't give me more than 25 years.
Pros can counter with - you plead guilty and we will go for life imprison without parole.
Perp can say yes or no. If perp says no, in this case, it is my opinion that the prosecutor will then proceed to trial with the DP on the table.
I don't think the Prosecution will give up the DP for anything less than LWOP.
