The attorney for an 84-year-old white man accused of shooting Ralph Yarl, a Black teenager who mistakenly went to his home, has requested a protective order to seal case records from being made public.

Andrew Lester was charged with first-degree assault and armed criminal action after he was accused of shooting 16-year-old Yarl on April 13. Yarl accidentally went to Lester’s north Kansas City, Missouri, home while trying to pick up his younger brothers, according to a probable cause statement obtained by the Kansas City Star.

According to a legal filing Monday, Lester’s attorney Steven Salmon is seeking a protective order and asked a court to prevent new information in the case from being made public. The shooting, which led to rallies and protests in the Kansas City area, has gained significant attention with critics saying Lester was given preferential treatment when police released him just two hours after he was arrested.

Salmon argued that the publicity of the case could cause difficulties for the trial and noted that Lester has received harassment since the incident, according to the legal filing.

Lester has pleaded not guilty to his charges and remains free on $20,000 bond. Yarl, who was shot in the head and an arm, is recovering at home after being hospitalized for three days.

Lester is scheduled to be in court June 1.
