In voir dire you can only strike three jurors. It could be the side that wanted her out was already out of strikes.
Not based on what happened to me today. Each side had 5 (and each used all 5).
It was an interesting process. Ultimately, I got struck. There were 30 of us in the selection process - 12 seated as jurors and I counted 18 alternates. We were asked a bunch of general questions and had to answer them 1 by 1. Then the prosecution and defense did a silent strike process (each got 5 strikes). 9 of the 12 original jurors were "replaced" by 9 of the 18 people sitting with me.
They were going to start the trial immediately after selection and they said the trial would take a few hours to 1 day. It was an evading police with excessive speed case and only 3 witnesses (3 police officers) were scheduled to be witnesses. Seemed like a very straightforward and efficient process.
Glad I didn't get picked but after hearing it would only be another 1 day max, I'm a little disappointed as it would have been cool to see things through. But I was back at work 3 hours after I showed up to the courthouse.
I got summoned and called it and it was for one trial so I did my duty and am out of the pool for now I would guess.
