In a May 2017 YouTube video, the accused Freeman High School shooter made a video showing him having a mock shootout with a friend. Caleb Sharpe created the video under his YouTube moniker Mongo Walker. The video in question is titled “J-Baumb kills Mongo.” It shows the suspect and a friend running with toy guns while shooting at each other. Sound effects are added to make the gunshots appear real. In one part of the video, Sharpe shoots a person who identifies himself as a civilian:

In June 2017, Sharpe uploaded a second video titled “The Second Round.” At the time of writing, the YouTube channel has been removed. A junior at Freeman, Paul Fricke, told the Spokesman, “We knew he had an assault rifle, because he uses it in his YouTube videos.”

On September 13, Caleb Sharpe was accused of going to Freeman High School in Rockland, Washington, where he was a sophomore and shooting dead one person while wounding three others. A sophomore, Michael Harper, 15, at Freeman High School told the Associated Press that Sharpe “had long been obsessed with past school shootings.” Harper added that at the start of the school year, Sharpe had brought a note to school saying that he “might get killed or jailed.” After that, classmates told counsellors about Sharpe. Harper went on to describe Sharpe as “nice and funny weird” while being popular with “many friends.”
