The Grover Cleveland Elementary School shooting took place on January 29, 1979, at a public elementary school in San Diego, California, United States. The principal and a custodian were killed; eight children and police officer Robert Robb 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. Charged as an adult, she pleaded guilty to two counts of murder and assault with a deadly weapon, and was given an indefinite sentence. As of September 2020, she remains in prison.A reporter reached Spencer by phone while she was still in the house after the shooting, and asked her why she had done it. She reportedly answered: "I don't like Mondays. This livens up the day," which inspired Bob Geldof and Johnnie Fingers to write the Boomtown Rats song "I Don't Like Mondays."
