16-year-old school shooter was asked why she shot 11 people. She said "I don't like Mondays"

On January 29, 1979, Cleveland Elementary School was attacked. The perpetrator was 16-year-old Brenda Anne Spencer, an introverted girl who lived across the street from the school.

She wounded 8 children and a police officer, and killed the principal and school janitor. When asked what her motive was for her actions, one of the things she said was "I don't like Mondays."

When police arrived on at the school, Brenda Anne Spencer had barricaded her house - the building that she was shooting at the school from. She repeatedly claimed that she was going to come out shooting, but eventually surrendered to the police.

Brenda Anne Spencer is still serving time in jail. She was tried as an adult for 2 counts of murder and assault with a deadly weapon.

Bob Geldof and The Boomtown Rats had a major hit with a song inspired by the events, written and performed soon after news of the shooting in San Diego. Titled "I Don't Like Mondays", it spent 4 weeks in the UK's #1 slot and was also popular in the United States, although local radio stations in San Diego refused to air the track for years after the shooting.
