The victim's mother Allison Jean said she wants to see the toxicology report for the off-duty officer to determine if any drugs were in her system at the time of the shooting. In addition to being charged with manslaughter, the shooting triggered an internal affairs investigation. A manager declined to indicate exactly when Guyger left and if she moved out voluntarily, according to the Dallas Morning News.
The Dallas County District Attorney's Office have requested three warrants for security footage that monitors the townhouses near the apartment where Officer Amber Guyger, 30, shot and killed 26-year-old Botham Jean.
Earlier, authorities released a video showing Guyger being booked into jail after she was arrested.
The Dallas Police Department fired Officer Amber Guyger on Monday, weeks after she fatally shot 26-year-old Botham Jean inside his own apartment on September 6.More news: Samsung Galaxy S10 will delight lovers of the classics

The arrest warrant affidavit - written by Texas Rangers, who took over the investigation - said Guyger found Jean's front door "slightly ajar", and then opened it by pushing a key into the door.
Jean, a native of Saint Lucia who worked for Pricewaterhouse Coopers in Dallas, was across the room when Guyger said she saw a "large silhouette" before giving verbal commands that were ignored before firing two shots. She then drew her weapon and fired twice at Jean, the affidavit said.
The case will be presented to a grand jury, which will decide whether to indict Guyger for manslaughter or a different charge. On the day of the shooting, Guyger's unit had arrested multiple suspects for armed robbery, he said.
Guyger was hired in November 2013 and assigned the Southeast Patrol Division.
