Atatiana Koquice Jefferson, a 28-year-old black woman, was fatally shot inside her home by a police officer in Fort Worth, Texas, United States, in the early morning of October 12, 2019.

[1][2] Police arrived at her home after a neighbor called a non-emergency number, stating that Jefferson's front door was open.

[3][2][4] On October 14, 2019, Officer Aaron Dean, the shooter, resigned from the Fort Worth Police Department and was arrested on a murder charge.

[20][21] It has been reported that just prior to 2:30 a.m on the morning of October 12, 2019, police received a "welfare call" from the neighborhood of Hillside Morningside, noting that the front door to someone's home was open.

[22] Body camera footage[23] released by the Fort Worth Police Department shows that two officers had walked quietly around the side of the home.

[17] Had Dean not voluntarily resigned and been fired instead, his separation paperwork would have been sent to the Texas Commission on Law Enforcement and would have reflected that he had been dishonorably discharged from the department.

[17][3] On October 25, 2019, Tarrant County District Attorney Sharen Wilson said evidence would also be presented to a grand jury for a formal indictment.

[33] In October 2020, Tarrant County judge David Hagerman set a tentative date of August 2021 for Dean's trial.

[34] After being initially delayed due to a backlog in the courts stemming from the COVID-19 pandemic, the trial was rescheduled in November 2021 to begin on January 10, 2022.

[36] At that time, Dean's defense attorneys filed a motion for a change of venue, claiming that local media coverage had made it impossible for their client to receive a fair and impartial trial in Tarrant County.

[37] On May 4, 2022, Judge Hagerman denied the defense's change of venue motion but granted another postponement, this one due to health issues being experienced by Dean's lead attorney.

[41] On June 9, Dean's attorneys filed a motion asking for Judge Hagerman to be replaced, claiming that he had "grown increasingly hostile, overbearing and rude" to them.

[42] On June 13, Tarrant County judge George Gallagher agreed to yet another delay in the trial pending the result of a hearing on the defense's recusal motion.

[43] On June 28, judge Lee Gabriel approved the defense's recusal motion, removing Hagerman from presiding over the trial.

[46] In November, Dean's attorneys filed another change of venue motion, claiming that their client could not get a fair trial in Tarrant County because former Fort Worth mayor Betsy Price and former police chief Ed Kraus had made public comments about the killing of Jefferson in the days after the shooting.

[49][50] Fort Worth Mayor Betsy Price called the event "tragic" and promised a "complete and thorough investigation" by police chief Ed Kraus.

[1] CBS News reported that the investigation would then be forwarded to the Law Enforcement Incident Team for the Tarrant County District Attorney.

During a press conference in the days following the shooting, Kraus became emotional as he compared the erosion of public trust to ants working to build an anthill, when "somebody comes with a hose and washes it away and they just have to start from scratch.
