Eric David Harris (April 9, 1981 – April 20, 1999) and Dylan Bennet Klebold (September 11, 1981 – April 20, 1999) were the high school seniors who committed the Columbine High School massacre. They killed 13 people and injured 21 others. Three people were also injured as they escaped the attack. Both Harris, 18 years old, and Klebold, 17, committed suicide at the site of the killings.
Eric David Harris was born in Wichita, Kansas. The Harris family relocated often as Eric's father, Wayne Harris, was a U.S. Air Force transport pilot. His mother, Katherine Ann Poole, was a homemaker. The family moved from Plattsburgh, New York to Littleton, Colorado in July 1993, when Wayne Harris retired from military service.
The Harris family lived in rented accommodations for the first three years that they lived in the Littleton area. During this time Eric met and befriended Dylan Klebold. In 1996, the Harris family purchased a house south of Columbine High School. Eric's older brother Kevin attended college at the University of Colorado at Boulder.
