What We Know About 1979 School Shooter Brenda Ann Spencer


When Brenda Ann Spencer said “I don’t like Mondays” after she fired a rifle from her house into an elementary school in 1979, her words became infamous. The 16-year-old girl killed two adults and injured eight children and a police officer. She was charged as an adult and pled guilty to two counts of murder, and was sentenced in 1980 to concurrent terms of 25-years-to-life in prison.

A December 2023 Reddit post revisited an old claim about the words Spencer was quoted as saying in the aftermath of the shooting. When asked why she did it, the post claimed, she replied: “I just don’t like Mondays.” Based on contemporaneous accounts, Spencer likely did say those words, though the evidence indicates she said them before she was arrested, not after (contrary to what’s implied in the Reddit post).

‘I Just Don’t Like Mondays’

To this day, one of the most unsettling aspects of that tragedy was the words Spencer reportedly said to a journalist around the same time she carried out the shooting. Over the phone, when asked why she did this, she said: “I just don’t like Mondays. Do you like Mondays? I did this because it’s a way to cheer up the day. Nobody likes Mondays.”

This quote became so famous it was the inspiration for the popular song “I Don’t Like Mondays” by the Boomtown Rats. Decades after her shooting spree, in an interview, Spencer would say she didn’t recall saying those words, as she had fragmented memories of that fateful day:

She told San Diego’s News 8 in 1993, “I don’t remember saying that. Right now we’re trying to find evidence that I did say that. I’d like to hear the tape. It really influenced how people saw me and thought about the whole case. […] I’d like to know that I actually did say that if I did.”

She added, “I’m [on] PCP [a hallucinogenic drug], you’re liable to say anything.” She described drinking the entire week before and missing school.

“That whole week ahead of time is pretty much a blur,” she said. Because of the drugs and alcohol, she claimed to have a “very fragmented memory of the whole day. Most of what I remember is what I’ve read from the police reports.”

In 1979 and 1980, a number of newspapers also used the quote, some stating that she “allegedly” said these words to a reporter.
