The city of Dallas has been dismissed from a federal lawsuit brought on by the parents of Botham Jean on Monday, according to CBS News. 

U.S. District Judge Barbara Lynn upheld a magistrate judge's decision by dismissing the city from the civil lawsuit because it failed "to state a claim upon which relief can be granted."

Lynn wrote in her brief ruling that the city was not liable for former officer Amber Guyger's action when she fatally shot Jean in his own apartment.

According to Dallas Morning News, the city could have been found liable for the accountant's death if Guyger used her authority as a police officer when she shot Jean. However, the city argued she was a startled resident thinking she was walking into her own home. 

The decision to remove the city from the suit now makes the 31-year-old former cop the sole defendant in the lawsuit which argues that she used excessive force and that better police training would have prevented the death of Jean.

The lawsuit also accuses the police department of implementing a "shoot first and ask questions later" policy.

"Essentially, Officer Guyger was ill-trained, and as a result, defaulted to the defective DPD policy: to use deadly force even when there existed no immediate threat of harm to themselves or others," the lawsuit stated.

According to CBS News, this now makes a large settlement for Jean's family unlikely. 

Guyger was found guilty of the September 2018 murder of 26-year-old Jean and sentenced to 10 years in prison in October. 

Jean was eating a bowl of ice cream and watching a football game in his apartment when Guyger, who was off duty but in uniform, entered forcefully, fatally striking him and causing public outrage. 

She was charged with manslaughter just three days after the shooting and was subsequently fired from the Dallas Police Department, as Blavity previously reported.

During the trial, Guyger said she thought she was walking into her own apartment and thought Jean was an intruder when she fired shots. Her apartment was one floor below Jean's.

She claimed she was tired, however, text messages revealed she was sexting with a fellow cop just moments before the shooting.

She initially described the shooting as "a tragic mistake" and said she was "completely devastated."

"I ask God for forgiveness, and I hate myself every single day … I wish he was the one with the gun who had killed me. I never wanted to take an innocent person's life," she said during the trial.

Guyger, who faced up to 99 years in prison, had her sentencing criticized for being too light.
