The high school students were planning an attack with pipe bombs and guns, police say.

Andrew Lester, 86, pleaded guilty last week to second-degree assault in the shooting of the teen boy in Kansas City in 2023.

The unarmed teenager was shot in April 2023 after knocking on the wrong door as he went to pick up his brothers. He survived the shooting.

Officer Mindy Cardwell inadvertently "put pressure on the trigger" of the pistol during the traffic stop.

Armed with a pistol, the attacker argued with the 16-year-old victim before opening fire, police say.

Police are still searching for a motive behind the attack at a private Christian school.

Police say clarifying a motive for Monday's deadly school shooting in the state's capital of Madison is a priority.

Two people were killed by the attacker, identified as a teenage girl who attended the school.
