Former Dallas police officer Amber Guyger's trial begins Monday in the death of Botham Jean, the 26-year-old man she shot on Sept. 6, 2018.

Jean was Guyger's upstairs neighbor at the South Side Flats apartments when she entered his home and fatally shot him. She told police she confused his apartment for hers and opened fire thinking he was an intruder.

Guyger will have a team of defense attorneys representing her while a team of prosecutors will present the murder case against her that has drawn national attention.

Here are a few key people to know in the case — inside the courtroom and out:

Amber Guyger

Guyger, 31, is a former Dallas police officer who will be tried for murder in the death of Jean. Before the shooting, Guyger had been the only female officer on an elite crime response team in the department's southeast division.

She was put on leave after the shooting and fired about two weeks later.

Guyger and her family have been mostly quiet and out of the public eye since the shooting, save for court dates when Guyger has had to come to the Frank Crowley Courts Building as her case has progressed.

Guyger's aunt wrote in an op-ed published by The Dallas Morning News that Guyger and her family are "devastated by what happened."

Jean loved music and singing and led worship sessions while he was in school every chance he got, friends said after his death.

Robert Rogers, Toby Shook and Michael Mowla

Robert Rogers, Toby Shook and Michael Mowla are all defense attorneys representing Guyger in the case.

Rogers regularly represents police officers in legal matters. He’s listed on the roster for attorneys who contract with the Texas Municipal Police Association to provide legal representation to officers.

Shook and Rogers are both former prosecutors, and Shook was a special prosecutor in the case of the 2013 murders of the Kaufman County district attorney, his wife and a top prosecutor.

Guyger's defense had tried to move her trial out of Dallas and into a nearby county instead, citing "media hysteria" surrounding the case in a motion filed in July. The judge presiding over the case denied the request a week before the trial.

Hermus has prosecuted several cases involving police officers, including the case of Ken Johnson, a former Farmers Branch officer who was off-duty when he chased down and killed a teenager he caught breaking into his car.

Johnson was convicted of murder and sentenced to 10 years in prison in January 2018.

He will be joined by several other prosecutors during the trial, including Jason Fine, who prosecuted the case in which a jury sentenced Wesley Mathews, a Richardson father accused of killing his 3-year-old daughter, Sherin, to life in prison.

State District Judge Tammy Kemp will preside over Guyger's trial. She has held the elected position since January 2015, and before that, she worked as a prosecutor and a defense attorney.

In 2013, Kemp was the lead prosecutor in a case in which a jury sentenced a man to die for drowning his two sons in a murky creek to get back at their mother.

He has taken on high-profile civil rights cases in the Dallas area, including representing the family of Jordan Edwards, the 15-year-old killed by former Balch Springs officer Roy Oliver, who was convicted of murder in Jordan’s death.

Some of his other high-profile clients include Mark Hughes, who was wrongly identified by police as a suspect in the July 7, 2016, ambush that killed five officers in downtown Dallas.

He also represented Jacqueline Craig, who was tackled by a Fort Worth police officer and arrested after she called 911 about a neighbor grabbing her young son by the neck.

Allison Jean

Allison Jean, Botham Jean's mother, lives in St. Lucia but has returned to Dallas for the trial. She has become a voice for her son since his death and has spoken publicly about the shooting several times, along with her husband and other children.
