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 Ann Spencer (born April 3, 1962), who lived in a house across the street from the school, was convicted of the shootings. She was tried as an adult, and pled guilty to two counts of murder and assault with a deadly weapon. She was given an indefinite sentence and remains in prison.
During the shooting, a reporter phoned houses near the school looking for information about what was going on. He reached Spencer, who freely admitted that she was the one doing the shooting. When asked why she was doing what she was doing, one of the things she was said to have told him was: “I don’t like Mondays.” The alleged comment was widely publicized; Spencer later said she did not recall making the remark.
