The Cleveland Elementary School shooting took place on January 29, 1979, in San Diego, California. Shots were fired at a public elementary school. The principal and a custodian were killed. Eight children and a police officer were injured. A 16-year-old girl, Brenda Spencer, who lived in a house across the street from the school, was convicted of the shootings. Tried as an adult, Spencer pled guilty to two counts of murder and assault with a deadly weapon, and was given an indefinite sentence. She is currently in prison. A reporter got through to Spencer after the shooting while she was still in the house. He said Spencer told him she carried out the shooting because she 'didn't like Mondays'. Spencer later said she did not recall making the remark.
