Columbine Gunman's Parents Fight Lawsuit

The parents of Columbine High School killer Dylan Klebold have asked a judge to throw out a lawsuit filed against them by families of victims, saying they are not to blame for their son’s actions.

In their response to an amended version of the complaint, Thomas and Susan Klebold denied they helped cause the carnage at Columbine by failing to properly supervise their son.

The Klebolds’ lawyers filed the response in U.S. District Court in Denver on Wednesday and it was made available Friday.

Klebold and Eric Harris, both seniors, attacked their school in Littleton on April 20, 1999, fatally shooting 12 students and a teacher and wounding two dozen others before killing themselves.

The lawsuit was filed by relatives of Daniel Rohrbough, Kelly Fleming, Matthew Kechter, Lauren Townsend, Kyle Velasquez and Cassie Bernall. All six were killed in the massacre.

Deny Claims of Victims’ Families

The Klebolds are among several defendants, who include Harris’ parents, Jefferson County sheriff’s officials and three people accused of providing the teenagers with the guns they used in the shootings.

The Klebolds denied the victims’ families’ claim that they knew or should have known their son’s inclination to carry out the attack.

They also denied claims they failed in their duties by allowing their son to amass weapons and build bombs in their home, associate with Harris and “author extremist writings of a hateful nature.”

The Klebolds have issued two written statements apologizing for the pain and suffering their son caused, once shortly after the massacre and once in the days before its anniversary.

On Wednesday, Mark Manes, who is serving a 6-year term for providing a gun to Harris and Klebold when they were minors, responded to four lawsuits against him, denying his negligence led to the deaths and injuries.
