Opening statements and trip to scene of shooting Tuesday

A jury of six white men, four white women and two black women will hear the murder case against former University of Cincinnati police officer Ray Tensing.

The jury, which also has four alternates who are white women, was selected after less than four hours of questions from the defense and prosecution.

Not much else is known about the jury that's about to hear what many consider to be the biggest case in Hamilton County history because juror identities are being protected.

Reporters were not permitted in the courtroom, and the live feed they watched in another courtroom had faulty audio for a large portion of the afternoon. Judge Megan Shanahan, who is presiding over the case, was not available for questions. Prosecutors, the defense and Tensing himself left the courthouse while reporters were ordered by deputies to stay inside the designated courtroom where the live feed was being streamed.

Jury selection began last week when more than 200 potential jurors were summoned to service and asked to fill out a 25-page questionnaire.

Prosecution: Tensing told police he 'purposely' killed DuBose

Forty-five of those potential jurors were in court Monday to be questioned in the courtroom. Nothing is publicly known about them.

Shanahan told them, after it came up that one man reported concerns about his safety on his questionnaire: "Many of you expressed concerns about serving on this jury. I want to assure you your identity will remain confidential."

The 12 men and women on Tuesday will begin hearing the case against Tensing, a former University of Cincinnati police officer who fatally shot Sam DuBose on July 19, 2015 as he drove away from a traffic stop. Tensing, 26, was fired. He is facing charges of murder and voluntary manslaughter, and has been free on a $1 million bond.

Jurors Monday saw a man dressed in a suit and tie, quietly taking notes. He was flanked by Mathews and his co-council, Gwen Callender. Callender has worked as the chief assistant counsel of the Ohio Fraternal Order of Police.

Black Lives Matter: Cincinnati held a rally outside the courthouse Monday, and the group is closely watching the proceedings because Tensing was a white officer who shot and killed a black man.

Brian Taylor, a member of the Black Lives Matter group's leadership, questioned the racial composition of the jury.

“People across ethnic groupings are capable of seeing the naked brutality of Ray Tensing, his tone and demeanor,” Taylor told The Enquirer. “But to have less than 18 percent of a jury by people of color in 2016 is a bad start.”

Taylor said "the black American experience” is vital in a jury.

“Only a justice system that continues to refuse to recognize the prejudices and racism still in existence would permit such a jury to be selected," he added. "I say this having no critique or bias towards the individuals and their capabilities to render justice.”

All potential jurors were asked what they already knew about the case. Some said they had read about it. Several said they already had seen the video, which has been widely publicized. A lone woman, who was eventually seated as a juror, admitted she had never heard anything about the case.

Prosecutors delivered the biggest revelation of the day. During questioning Assistant Prosecutor Rick Gibson revealed Tensing told police detectives he "purposely caused the death of Sam DuBose." It was the first time the prosecutors publicly talked about Tensing's police interview.

Mathews asked several questions about what jurors would think if Tensing didn't testify, which is Tensing's right under the law. But then Mathews admitted it was a "trick question," saying Tensing would testify.

Both sides reminded jurors the decision had to be based on the evidence presented in the courtroom. And Mathews added no decision should be made based on on Tensing's or DuBose's race.

"This case is not about the color of any man’s skin," Mathews said. "It’s about the facts."

Questions showed that everything about potential jurors was scrutinized, including their social media accounts. It was revealed that one woman posted on Facebook last week, "Help get me out of here." The woman was eventually dismissed.

Jurors were sworn in at the end of the day Monday, around 4 p.m. They're set to return Tuesday at 9 a.m. They'll be driven to the scene of the Mount Auburn shooting. Shanahan has said the trial each day will last until about 1 p.m. Opening statements are also expected Tuesday.
