Robyn K. Anderson was a friend to Eric Harris and Dylan Klebold, the perpetrators of the Columbine High School Massacre. She purchased three of the four firearms they would use in the massacre, not knowing of their use until then. Anderson was Klebold's 1999 prom date.


She was born somewhere in Colorado in 1981. She lived in Denver and moved to Littleton, Colorado in 1995. She attended Ken Caryl Middle School for a year before going to Columbine High.

Robyn Anderson was a close friend to Dylan and partially knew Eric. In November or December of 1998, Anderson and both boys went to a gun show and Anderson purchased three of the guns for Eric and Dylan, who were both under aged and could not acquire them themselves. These guns were the Hi-point Carbine rifle, the pump action shotgun, and the double barrelled shotgun. She was unaware what they intended to use the guns for at the time. Once the guns were purchased, Eric and Dylan would saw the barrels of their shotguns for easy concealability.

On April 17, 1999, Anderson went to the Columbine senior prom with Dylan Klebold as her date. She said that boasted to friends she really wanted to bring him to the prom despite Dylan initially refusing to go. Nothing seemed wrong with Dylan that day, according to her.

Columbine High School Massacre

Robyn Anderson was in school at the time the massacre began but she did not run into the boys as they entered the building. Anderson felt suspicious of who would commit the massacre in the first place.

After the massacre ended, she was spoken to authorities about her connection with the shooters. She told them every detail she remembered including how she was unaware of what they intended to do with the guns. Due to her cooperation with the authorities, no charges were brought against her.

House Judiciary Committee

In January 2000, nearly a year later after the shootings, she told the House Judiciary Committee that a background check would have prevented her from even thinking about getting the guns for Harris and Klebold. It is explained here

Eric Harris and Dylan Klebold had gone to the Tanner gun show on Saturday and they took me back with them on Sunday. I remember this as being in November or December of 1998. When Eric and Dylan had gone the previous day, a dealer told them that they needed to bring someone back who was 18. They were both 17 at the time. This was a private dealer - not a licensed dealer. While we were walking around, Eric and Dylan kept asking sellers if they were private or licensed. They wanted to buy their guns from someone who was private - and not licensed - because there would be no paperwork or background check. At one point Eric was interested in a gun from a licensed dealer. The dealer asked me if I would fill out some paperwork and I said, "No, I didn't feel comfortable with that. I didn't want to put my name on something that I wasn't going to have control of."They bought guns from three sellers. They were all private. They paid cash. There was no receipt. I was not asked any questions at all. There was no background check. All I had to do was show my driver's license to prove that I was 18. Dylan got a shotgun. Eric got a shotgun and a black rifle that he bought clips for. He was able to buy clips and ammunition without me having to show any I.D. The sellers didn't write down any information. I would not have bought a gun for Eric and Dylan if I had had to give any personal information or submit to any kind of check at all. I think it was clear to the sellers that the guns were for Eric and Dylan. They were the ones asking all the questions and handling the guns. I had no idea what they were eventually going to do with the guns. When I look back at it, I think I was kind of naive. I wish a law requiring background checks had been in effect at the time. I don't know if Eric and Dylan would have been able to get guns from another source, but I would not have helped them. It was too easy. I wish it had been more difficult. I wouldn't have helped them buy the guns if I had faced a background check.
