Amber Guyger, 31, the former Dallas police officer convicted Tuesday of murdering an unarmed man in his own home last year, was sentenced Wednesday to 10 years behind bars.

Guyger fatally shot Botham Shem Jean, 26, in his apartment, then claimed she mistook his apartment for her own, which was located one floor below. Guyger pleaded not guilty and did not testify during the punishment phase of the trial.

Judge Tammy Kemp instructed jurors to decide on a sentence of between five and 99 years unless they agreed that Jeans death was the result of an unplanned sudden passion, a classification that comes with a penalty of two to 20 years.

We the jury find unanimously that the defendant did not cause the death of Botham Jean while under the immediate influence of sudden passion, Kemp said, reading from the jurys verdict. The jury deliberated for an hour and a half before coming to a decision.

Prosecutors asked for at least 28 years, one for each year of Jeans life, had it not been cut short. Guyger will have to serve at least half her sentence five years before she can be considered for parole.

Angry, emotional chants of No justice, no peace echoed in the hallway outside the courtroom by those who felt the sentence was too short for Guyger.

Ten years? Ten years is a slap in the face, one woman shouted.

Botham Jeans younger brother said in his victim impact statement that he forgave her and hoped she would give her life to Jesus. He also stepped off the podium to embrace Guyger and said he did not think she should go to jail.

I want the best for you, Brandt Jean said. Because I know as well thats exactly what Botham would want for you. And the best would be to give your life to Christ.

After their embrace, Kemp stepped off the bench to give Guyger her personal Bible and told her to read it. She then hugged Guyger, a move that appeared controversial to those paying attention to the verdict.

Jeans mother, Allison Jean, told reporters after the sentencing that the 10 years are for Guyger to reflect on her life but that Dallas police must make changes so that the corruption that we saw during this process must stop.

If Amber Guyger was trained not to shoot in the heart, my son would be standing here today, she said. Every single one of you, citizens of Dallas ... need to know what to do to get your city right.

Allison Jean took the witness stand earlier Tuesday as family photos were displayed for the court. I have to try to keep the family together because everybodys in pain. Ive had to get counseling, she said.

Botham Jean, from the Caribbean nation of St. Lucia, left home to pursue higher education even though his mother wanted him to stay near. She described her son as a headstrong young man who enjoyed using his talents to help others.
