Overview
- Gunfire and screams were reported just after 5:12 p.m. on Monday at the Chico branch of the Butte County Library and officers entered the building within minutes to secure the scene.
- An 18‑year‑old Chico resident, Bradley Scott Sayer, was taken into custody outside the library without officers firing and was booked on suspicion of two counts of murder.
- Investigators say Sayer scoped the building, returned with a shotgun and fired about eight rounds, and they found two additional firearms in his vehicle that were registered to his family.
- Authorities identified the two men killed as 46‑year‑old Jacob Hull and 74‑year‑old Robert Johnson and said a juvenile suffered non‑life‑threatening injuries and was treated and released to family.
- Local, county and federal agencies are collecting physical and digital evidence, all Butte County library branches were temporarily closed, and officials are weighing further charges and security changes as the community grieves.
