A 16-year-old girl, Brenda Spencer, was the country's first high-profile school shooter. She killed the principal and a custodian at Grover Cleveland Elementary School in San Diego, California, on January 29, 1979. At a parole hearing in 2001, she said she felt partially responsible for school shootings that have happened since. One of the students on the scene wasn't inspired by her hateful actions but he was inspired by the courage of his school's faculty and staff that day. He became a teacher himself because of that day.
