The suspect in the murder of two Arizona teens posted videos of himself firing a homemade weapon. Thomas Brown’s videos were on a YouTube channel he uses to promote his 3D printing business. Police say Brown shot and killed Evan Clark and Pandora Kjolsrud, who were on a Memorial Day camping trip to Mount Ord. Brown served in the Arizona National Guard for nine years, leaving in 2022 with the rank of Staff Sergeant.
