A White former Dallas police officer was indicated on murder charges Nov. 30, nearly three months after she fatally shot an unarmed Black neighbor whose apartment she said she entered by mistake, believing it to be her own.

Amber Guyger told fellow officers that she opened fire when Botham Jean appeared in the darkness.

Jean’s relatives joined Dallas County District Attorney Faith Johnson for the announcement of the charges. Jean, a 26-year-old native of the Caribbean island nation of St. Lucia, attended college in Arkansas and had been working in Dallas for accounting and consulting firm PwC.

“I truly believe that she inflicted tremendous evil on my son,” Jean’s mother, Allison said after the announcement. “He didn’t deserve it. He was seated in his own apartment.”

Guyger was arrested on a manslaughter charge three days after the Sept. 6 shooting, prompting criticism that the original charge was too lenient. But Johnson said at the time that the grand jury could upgrade the charges, which it did Friday.

“When you look at the facts of this case, we thought that it was murder all along,” Johnson said.

After finishing her shift, Guyger told investigators , she returned home in uniform and parked on the fourth floor of her apartment complex’s garage, rather than the third floor, where her unit was located, according to an affidavit prepared by the Texas Rangers.

She said she got to what she thought was her apartment — Jean’s was directly above hers — and found the door ajar. She opened it to find a figure standing in the darkness. She said she pulled her gun and fired twice after the person ignored her commands.

Guyger has since been fired from the department, and Jean’s family has filed a lawsuit against Guyger and the city of Dallas. The federal suit argues that Guyger used excessive force in the shooting and contends the department did not give her adequate training.

The circumstances of the shooting sparked outrage and led many to question Gugyer’s account. Critics, including Jean’s family, also wondered why it took three days for Guyger to be charged, why she was not taken into custody immediately after the shooting and whether race played a factor in her decision to use deadly force.

Guyger’s attorney, Robert Rogers, did not immediately return a phone call seeking comment on the indictment.

Jean’s killing thrust Dallas into the national conversation about the intersection of race and law enforcement, a dialogue revived by the high-profile trials of officers charged with murder in police shootings.

In October, White Chicago officer Jason Van Dyke was found guilty of second-degree murder in the 2014 on-duty shooting of Black teenager Laquan McDonald. Van Dyke shot McDonald 16 times.

And in August, White former Dallas-area officer Roy Oliver was convicted of murder for firing into a car filled with Black teenagers leaving a house party in 2017. Fifteen-year-old Jordan Edwards was fatally shot.
