CHICO, CA (MPG) – Two adults were killed and a juvenile was injured Monday afternoon after a shooting inside the Butte County Library in Chico, according to the Chico Police Department.

The Chico Police and Fire Communications Center received multiple 911 calls at 5:12 p.m. on June 22 reporting gunshots and screams coming from inside the library.

Officers arrived at the library at 5:18 p.m. and entered the building shortly afterward. As officers moved into the library through the front entrance, the suspected gunman exited through the rear of the building, where a perimeter had already been established. Police said the suspect was taken into custody without incident.

Authorities confirmed that two adults died at the scene. A juvenile victim was transported to Enloe Health with injuries that were not considered life-threatening.

On Tuesday, Chico police identified the suspect as 18-year-old Chico resident Bradley Scott Sayer. He was arrested and booked into the Butte County Jail on two counts of murder.

Investigators from the Chico Police Department, Butte County Sheriff’s Office and Federal Bureau of Investigation are continuing to collect evidence, conduct interviews and review the circumstances surrounding the shooting.

Police said investigators have determined Sayer acted alone and found no indication that he had any prior relationship or connection to the victims who were inside the library at the time of the attack.

According to investigators, Sayer’s apparent motive was a desire to carry out a shooting similar to the 1999 Columbine High School massacre in Colorado.

The investigation remains active, and authorities said additional information may be released as it becomes available.

First Avenue was closed between Sheridan Avenue and Arbutus Avenue for several hours Monday evening while investigators processed the crime scene.

The Chico Police Department thanked assisting agencies, including the Butte County Sheriff’s Office, California State Parks, California Highway Patrol, Cal Fire, Butte College, the FBI and the California Department of Corrections and Rehabilitation.

Anyone with information related to the case is asked to contact the Chico Police Department Detective Bureau at 530-897-5820.
