• Six-year-old Dedric Owens fatally shot classmate Kayla Rolland in a stairwell at Buell Elementary School in Mount Morris Township, Mich., after reportedly saying to her, “I don’t like you.” He was taken into police custody soon after. Ms. Rolland is believed to be the youngest school-shooting victim in US history, and Mr. Owens is the youngest shooter. Owens's uncle, the owner of the gun, eventually pleaded no contest to involuntary manslaughter and spent two years and five months in prison before being released on probation.
