Special Report: Dozens of mock trials conducted in preparation for Slender Man stabbing trial

WAUKESHA Wis. (CBS 58) -- The Slender Man case made headlines nationwide. Both Morgan Geyser and Anissa Weier will likely not face jail time for stabbing a classmate after taking a plea deal. 

We're now learning how Geyser's attorneys prepared for trial. It's a process very similar to what happens on the CBS drama "Bull."

"Does anyone on the panel have any medical problems that would prevent you from devoting your full attention to this trial?" said Marquette law student Chelsea Pierski.

In their last year of law school,  Pierski and her classmates are using Marquette's mock trial room as they prepare for the real thing one day.

"Are you both prepared to be a juror if the case should happen to continue forward?" asks Joe Esposito to a panel of mock-jurors.

The concept of a mock trial isn't just for amateurs. Practicing lawyers conduct them too.

"It's a good way to get a feel for what you're facing in the real case," said Robert Habush, Marquette Adjunct Professor, and Personal Injury Attorney.

Jury consulting is now a household term thanks to the CBS prime time drama "Bull."

Dozens of mock trials have been conducted for Morgan Geyser. A well-known, local case, Geyser and her classmate, Anissa Weier are accused of stabbing another classmate to please the fictional character Slender Man. 

With details of the crime in the media and on the internet, Morgan Geyser's legal team brought on two real-life Dr. Bulls, and they're no stranger to the courtroom. 

Amy Singer works out of Miami, Florida consulted for the OJ Simpson, Michael Jackson, and Casey Anthony trials. Rob Rosenberg works from Waukesha County. He was in the courtroom when Saved by the Bell actor Dustin Diamond was charged a few years ago.

Those who've conducted mock trials for real cases say Bull's got a few things wrong. While Dr. Bull and his team may hack into phones or bug watches, real jury consultants cannot cross any privacy lines, but they still do their research.

"We're not interested in whether they shop at Kmart or JCPenny. What we're interested in are what are their value beliefs," said Singer.

Singer has technology that looks at public information of potential jurors. She says some examples of what they might find are petitions singed on change.org or comments someone makes on Facebook or Youtube.

Amy and Rob don't use a mock trial room. They find their mock jurors on twitter and then stream different parts of the trial. 

"They're in the comfort of their home... they could be wearing their pajamas," said Rob Rosenberg.

"In a case like this, we found that a lot of people might misunderstand the facts of the case based on what they see on tv and what they see on the news."

Even though going to trial is where their hard work shows, jury consultants know a mock trial isn't always practice for the real thing.

"They pay me to find the argument to which there is not counter-argument... sometimes I'll say fold. Know when to hold, know when to fold because... sometimes we're wrong," said Amy Singer.

Geyser's lawyers couldn't go into specifics of what was covered in the mock trials but they will elaborate after Thursday's plea hearing.
