Officer thought she was in her own apartment, warrant says 
 
 Guyger, who is white, was off-duty when she encountered Jean , an 26-year-old unarmed black man, in his apartment on September 6, police said. The indictment of Amber Guyger comes more than two months after she was arrested in the shooting death of Botham Shem Jean at the Dallas apartment complex where both lived -- a killing that sparked days of protests. Guyger was arrested September 9 on suspicion on manslaughter, and was released from the Kaufman County Jail after posting a $300,000 bond. Guyger was arrested after the September shooting and charged with manslaughter by the Texas Rangers, the lead investigative agency, Dallas County District Attorney Faith Johnson said at a news conference. Guyger had already been arrested again and released on bond, Johnson said at the news conference. Asked why the grand jury indicted Guyger on a murder charge, Johnson said, “We presented the evidence and explained the law.” She added that the law prohibits her from talking about the evidence presented to the grand jury.

 Johnson said that at the moment of the shooting, the action was intentional. The court records Friday showed both a manslaughter and murder charge entered in Guyger's file, but a clerk of court clerk confirmed that the murder charge is the one prosecutors are moving forward on. She described seeing a large silhouette and, believing there was an intruder in her apartment, drew her firearm. Johnson, who was voted out of office in the Nov. 6 election, will not see the case through to a trial and said Friday that she “trusts the DA-elect will continue to represent this family (and all of Dallas County) as he seeks justice for victims.” 
 
 Johnson also spoke about why it took her office two months to bring the case in front of a grand jury. "We are confident that a dispassionate jury in a fair forum will objectively apply the law to the facts and find Amber not guilty." The Dallas Police Department fired Guyger during a hearing September 24, the police chief said. On Friday, Police Chief U. Renee Hall released a statement saying every person in the department continues to “feel anguish about this difficult and tragic event that occurred.” 
 
 “We have developed the framework for policy change, have supported the restructuring of the Citizen Review Board, pushed to exceed the basic requirements of implicit bias training, and have relied on input from our employee advisory and community advisory boards,” she said. “We have more work to do and we remain committed to improving our relationships throughout the city.” 
 
 
 
 
 
 The Lawyers’ Committee for Civil Rights Under Law said the indictment is an “important reminder that police derive their authority from the people and it is the people, functioning as members of grand juries, who must insist that police authority be exercised in a lawful manner and who must hold police accountable when they fail to do so.” 
 
 Jean was a native of the Caribbean island of St. Lucia. Jean's parents filed a lawsuit in federal court against Guyger and the city last month, alleging Guyger used excessive force.
– In September, Amber Guyger, at that time a Dallas police officer, walked into the apartment of Botham Shem Jean and shot the 26-year-old to death. Guyger lived in the same building as Jean and claimed that she thought she was entering her own unit and believed he was an intruder. On Friday, a grand jury indicted Guyger on a murder charge, CNN reports. Texas Rangers had initially arrested Guyger on a manslaughter charge. But Dallas County DA Faith Johnson said at a news conference, the grand jury settled on the more serious charge after “we presented the evidence and we explained the law.” The Texas Rangers “chose to file this case as manslaughter,” she said, per the Star-Telegram. “We did our own investigation. We thought it was murder all along.” Johnson said that murder involves causing a death “intentionally and knowingly,” as opposed to manslaughter, which results from recklessness. “At the moment of the shooting it was a knowing … offense,” she said per CNN. Jean, who was a native of St. Lucia in the Caribbean, went to college in Arkansas before moving to Dallas to work for PriceWaterHouseCoopers. His family filed a lawsuit against the city and police department in October. (This officer was fired for not shooting someone.)
