Dylan Klebold was one of the two perpetrators involved in the Columbine High School shooting that occurred on April 20, 1999. Born on September 11, 1981, in Lakewood, Colorado, he was a student at Columbine High School and was known to be quiet and reserved. Along with his accomplice, he planned and executed a tragic attack that resulted in the deaths of 13 people and injuries to many others. Klebold and his partner, Eric Harris, used firearms and explosives during the attack, which shocked the nation and led to widespread discussions about school safety, bullying, and gun control. After the shooting, Klebold took his own life, leaving behind a complex legacy that continues to be analyzed in discussions about youth violence and mental health.
