Eric Harris (individual)
Eric Harris was a 17-year-old high school student known for his involvement in the Columbine High School shooting in 1999, along with Dylan Klebold. The attack resulted in the deaths of 13 people and injuries to many others before Harris and Klebold took their own lives. Harris was often described as intelligent but troubled, with documented mental health issues and signs of anger and depression. His actions, along with Klebold's, led to widespread concern about youth violence, mental health, and school safety, and have been studied extensively to understand and prevent such tragedies.
