An 18-year-old suspect, Bradley Scott Sayer, has been arrested following a deadly shooting at the Butte County Library in Chico, California, on Monday evening, 22 June. Police say the suspect was allegedly motivated by a desire to re-enact the 1999 Columbine High School massacre.
Police recovered a shotgun registered to Sayer's family, which was the weapon allegedly used in the attack and also discovered additional firearms inside the suspect's vehicle.
