Brenda Spencer

As of April 2020, she remains in prison and is housed at the California Institution for Women in Chino.

The Lifetime Movies, series Killer Kids released an episode "Deadly Compulsion" depicting Spencer's crimes, first air date: September 3, 2014.

The 2008 book Ceremonial Violence: A Psychological Explanation of School Shootings, by Jonathan Fast, analyzes the Cleveland Elementary shooting and four other cases from a psychological perspective. These are the other shootings reported on: the Columbine High School shooting, the shootings at Simon's Rock College, the Bethel Regional High School shooting, and the Pearl High School shooting.

The Investigation Discovery network portrayed Brenda Spencer's crimes in one of the three cases presented in the premiere episode of season 2 on the crime documentary series Deadly Women, titled "Thrill Killers", first air date: October 9, 2008.

Spencer was the inspiration for the song "I Don't Like Mondays," written by Bob Geldof and Johnnie Fingers for their band the Boomtown Rats, which was released later that year. I Don't Like Mondays was also the title of a 2006 television documentary about the event.

The 1999 book Babyface Killers: Horrifying True Stories of America's Youngest Murderers, authored by Clifford L. Linedecker dedicates the book's prologue to Spencer and refers to her crimes in multiple chapters.

Under the terms of her indeterminate sentence, Spencer became eligible for hearings to consider her suitability for parole in 1993. Normally, very few people convicted on a charge of murder were able to obtain parole in California before 2011. As of December 2015, she has been unsuccessful at four parole board hearings. At her first hearing, Spencer said she had hoped police would shoot her and that she had been a user of alcohol and drugs at the time of the crime, although the results of drug tests done when she was taken into custody were negative. In her 2001 hearing, Spencer first claimed that her father had been subjecting her to beatings and sexual abuse, but he said the allegations were not true. The parole board chairman said that as she had not previously told any prison staff about the allegations, he doubted whether they were true. In 2005, a San Diego deputy district attorney cited an incident of self-harm from four years earlier when Spencer's girlfriend was released from jail, as showing that she was psychotic and unfit to be released. The self-harm is commonly reported as scratching the words "courage" and "pride" into her own skin; however, Spencer corrected this during her parole hearing as "runes" reading "Unforgiven" and "alone." In 2009, the board again refused her application for parole and ruled it would be ten years before she would be considered again. She is eligible for a Parole Suitability Hearing in September 2021.

On January 17, 1989, almost ten years after the events at San Diego's Grover Cleveland Elementary, there was another shooting at a school named Grover Cleveland Elementary, this one in Stockton, California. Five students were killed and thirty were injured. One survivor of the 1979 shooting described herself as "shocked, saddened, horrified" by the eerie similarities to their own traumatic experience.

A plaque and flagpole were erected at Cleveland Elementary in memory of the shooting victims. The school was closed in 1983, along with a dozen other schools around the city, due to declining enrollment. In the ensuing decades, it was leased to several charter and private schools. From 2005 to 2017, it housed the Magnolia Science Academy, a public charter middle school serving students in grades 6–8.

The 1982 Japanese-American documentary film The Killing of America depicts the incident.

Spencer was charged as an adult and pleaded guilty to two counts of murder and assault with a deadly weapon. On April 4, 1980, a day after her 18th birthday, she was sentenced to 25 years to life. In prison, Spencer was diagnosed as an epileptic and received medication to treat her epilepsy and depression. While at the California Institution for Women in Chino, she worked repairing electronic equipment.

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 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. 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 May 2020, she remains in prison.

On the morning of Monday, January 29, 1979, Spencer began shooting at children waiting for Principal Burton Wragg (age 53) to open the gates to Grover Cleveland Elementary. She injured eight children. Spencer shot and killed Wragg as he tried to help children. She also killed custodian Mike Suchar (age 56) as he tried to pull a student to safety. A police officer (age 28), responding to a call for assistance during the incident, was wounded in the neck as he arrived. Further casualties were avoided only because the police obstructed her line of fire by moving a garbage truck in front of her house.

Bob Geldof, then the lead singer of the Boomtown Rats, read about the incident when a news story about it came off the telex at WRAS-FM, the campus radio station at Georgia State University in Atlanta. He was particularly struck by Spencer's claim that she did it because she did not like Mondays, and began writing a song about it, also incorporating the reporters' "Tell me why?," called "I Don't Like Mondays". It was published in July 1979 and was number one for four weeks in the United Kingdom, and was the band's biggest hit in their native Ireland. Although it did not make the Top 40 in the U.S., it still received extensive radio airplay (outside of the San Diego area) despite the Spencer family's efforts to prevent it. Geldof has later mentioned that, "[Spencer] wrote to me saying 'she was glad she'd done it because I'd made her famous,' which is not a good thing to live with."

In early 1978, staff at a facility for problem students, into which Spencer had been referred for truancy, informed her parents that she was suicidal. That summer, Spencer, who was known to hunt birds in the neighborhood, was arrested for shooting out the windows of Grover Cleveland Elementary with a BB gun and for burglary. In December, a psychiatric evaluation arranged by her probation officer recommended that Spencer be admitted to a mental hospital for depression, but her father refused to give permission. For Christmas 1978, he gave her a Ruger 10/22 semi-automatic .22 caliber rifle with a telescopic sight and 500 rounds of ammunition. Spencer later said, "I asked for a radio and he bought me a gun." When asked why he might have done that, she answered, "I felt like he wanted me to kill myself."

Brenda Spencer (born April 3, 1962) lived in the San Carlos neighborhood of San Diego, California in a house across the street from Grover Cleveland Elementary School in the San Diego Unified School District. Age 16, she was 5'2" (157 cm) and had bright red hair. After her parents separated, she lived with her father, Wallace Spencer, in poverty. They slept on a single mattress on the living room floor, with empty alcohol bottles throughout the house.
