On November 30, 2018, Guyger was indicted on murder charges by a
Dallas County grand jury. On September 22, 2019, the day before the trial began,
Dallas County District Attorney John Creuzot took part in an interview regarding the trial in spite of a gag order issued by Judge Tammy Kemp in January of that year. After questioning jurors, who reported that they had not seen the interview or other media coverage of the trial, Kemp denied the defense's motion for a
mistrial, and sequestered the jury. Manslaughter charges would have merely required proof of recklessness, while murder charges require proof that the defendant intended to cause either great bodily harm or death (with death resulting). On October 1, 2019, Guyger was found guilty of murder. The jury deliberated for six hours to reach the verdict of murder. During the sentencing hearing, Jean's mother Allison provided emotional testimony and some of Guyger's text messages and social media posts that were "racist and offensive" were shared. Jean's younger brother Brandt forgave and hugged Guyger during her sentencing. Jean's father Bertrum also stated that he forgave Guyger but had wanted a stiffer sentence. Guyger's legal bills were paid by the
Dallas Police Association, a
police union which serves Dallas officers. On October 16, 2019, Guyger's attorneys filed a notice of appeal requesting a new trial. On August 7, 2020, Guyger's attorneys filed an appeal, alleging that insufficient evidence existed to convict her of murder. The appeal sought either an acquittal, or a reduction in charge to criminally negligent homicide with a new hearing for sentencing on the reduced charge. On August 5, 2021, the
Fifth Court of Appeals of Texas upheld Guyger's murder conviction, unanimously holding that the jury verdict was reasonable and Guyger's own testimony supported the murder charge. On November 17 of that year, the court withdrew its previous opinion, but again upheld her murder conviction using similar reasoning, stating that her defense that she had unknowingly entered the wrong apartment did not justify the lesser charge of criminally negligent homicide. Her appeal to the
Texas Court of Criminal Appeals, the
court of last resort for criminal cases in the state, was denied. Guyger is currently imprisoned in the
Patrick O'Daniel Unit (formerly the Mountain View Unit). She was eligible for release in September 2024, after serving half her sentence, although her full sentence runs until September 2029. Guyger was denied parole in October 2024. She will be eligible for release again in 2026.
Controversy regarding police car camera After the shooting, Guyger was detained and placed in the patrol car of Dallas police sergeant Breanna Valentine, who was then approached by Sergeant Mike Mata, Valentine's superior and president of the Dallas Police Association. Mata told Valentine to shut off the in-car camera, which recorded sound, so that he and Guyger could talk privately, and Valentine complied. Mata testified at Guyger's trial that turning off the camera was standard procedure intended to protect Guyger's
attorney–client privilege, as she was planning to call her attorney. Guyger's defense attorney endorsed Mata's statement,
Controversies involving witnesses On January 31, 2019,
ABC News reported that a female witness—identified only as "Bunny" — had taken a video of Guyger's actions immediately after the shooting. The witness claimed to have been harassed and threatened by unidentified
Internet trolls after providing the video to the Dallas County District Attorney's Office and later posting it on social media. On October 4, 2019, key prosecution witness and Jean's across-the-hall neighbor, Joshua Brown, was shot and killed in the parking lot of another apartment complex he had moved to, about from where Jean and Guyger had lived. Witnesses could not describe the shooter or shooters, only the vehicle they drove. On October 8, Dallas police announced that they had identified three suspects in Brown's killing and had arrested one of them, and that the suspects were engaged in a drug deal with Brown when he was shot. A search of Brown's apartment yielded of
marijuana, of
THC cartridges and $4,000 in cash; however, advocates questioned police claims that the three men had traveled from
Alexandria, Louisiana, to purchase drugs from Brown, and an attorney representing Brown's family called for an independent investigation by another agency. Dallas Assistant Police Chief Avery Brown denied that Joshua Brown's death was related to Guyger's trial. A second suspect was arrested the next day, and on December 8, all three men were indicted on charges of
capital murder, although one of them remained at large. == Civil trial ==
