Overview
- Police say multiple 911 calls reporting gunshots and screams brought officers to the Chico branch of the Butte County Library and that the suspect was taken into custody after fleeing out the back of the building during entry on Monday evening.
- Two adults were confirmed dead and a juvenile was treated at a hospital for non‑life‑threatening injuries, with victim names withheld pending family notification.
- Authorities later identified the suspect as 18‑year‑old Bradley Scott Sayer and booked him on suspicion of two counts of murder; officials say a single firearm was used and no shots were exchanged with officers.
- The Chico Police Department is leading a multiagency investigation with assistance from the Butte County Sheriff’s Office and the FBI, investigators have not disclosed a motive and they urge anyone with information to contact police.
- Butte County closed all library branches, set up a family reunification center and kept streets near Sherman Avenue restricted as the community copes with the violence and officials process evidence and plan next steps.
