In October 2020, Tarrant County judge David Hagerman set a tentative date of August 2021 for Dean's trial. 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. In December 2021, the trial was delayed again, to May 2022, due to two defense witnesses being unavailable in January. 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. 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. The new trial date was set for June 23. On May 16, Dean's attorneys filed a motion asking Judge Hagerman for yet another delay, as they claimed to have higher priority cases in May and June and "cannot be ready" by June 23 because of the preparation time required to meet their caseload. During a hearing on June 3, Dean's attorneys claimed their own personal vacation plans should be considered for a further delay of the trial, but Hagerman denied their request and confirmed that the trial would begin on June 23. 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. 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. On June 28, judge Lee Gabriel approved the defense's recusal motion, removing Hagerman from presiding over the trial. After Hagerman's recusal, the trial was assigned to Judge Gallagher and delayed again. On August 18, 2022, a new trial date of December 5 was set, with jury selection slated to begin on November 28. 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. The second change of venue motion was denied and the trial began on December 5, 2022. On December 15, 2022, Dean was found not guilty of murder but guilty of the
lesser included offense of
manslaughter. == Federal civil rights lawsuit ==
