The trial of Anrietta Geske in the crash deaths of two young women could be a very emotional but also technical trial.

As opening statements start Tuesday in Brown County court, both sides will focus on different agendas, says legal analyst Tricia Nell.

For the prosecution, it's about proving guilt on two levels:

"They're going to have to lay out the fact that this defendant was over the legal limit, which in Wisconsin is 0.08, and that that was the cause of the crash, and secondly and/or reckless endangerment, and that would be showing utter disregard for human life, and to do that the prosecution is going to have to lay out that this case involved speed, alcohol, and maybe some negligence on behalf of this defendant."

Nell believes the key to the entire case will be Geske's blood-alcohol level.

She expects the defense to use multiple experts to convince the jury Geske's blood-alcohol level was never above the legal limit since she tested below the limit two hours after the fatal crash.

"In fact, in most drunk-driving cases there's a two-hour window where a person's alcohol content can go up or down based upon when the last time they consumed alcohol was and what they were drinking, as well as their weight and body content," Nell said.

Explaining that to a jury could get very technical, Nell said, which is why she foresees a slew of experts testifying.

"At the end of the day, stats do show that the battle of the experts often times knock each other out and people go back to the bottom line of what happened in this case."

The prosecution no doubt will make this about the two victims, said Nell, using their pictures and images of the crash.

And we may learn new details, like where Geske was before the crash and what prescription medication she may have been taking. That, she said, could have a lasting impact on the jury.

"So there's quite a bias for people using medication or mixing alcohol with meds, and in fact I believe people have strong views one way or the other," Nell said.
