Daniel Mauser was shy, but he still decided to join the debate team. He wasn’t that athletic, but he still challenged himself by signing up for the cross country team. Born on June 25, 1983, he was bright, curious, and obsessed with numerous video games and computer games.

And even though Mauser was just 15 years old, he was deeply interested in current events. Weeks before he died, he informed his father of a number of loopholes in the Brady Bill, a gun control law established in 1993. Little did Mauser know that one of those loopholes would lead to his murder.

Because his one close friend at school had a different lunch hour, Daniel Mauser habitually ate his lunch quickly and then went to the library to read or study before his afternoon classes. On the afternoon of April 20, 1999, Mauser was in the library as usual when the shooting began.

Daniel Mauser And A Computer

Hiding under a table, Mauser heard the deaths of several other Columbine shooting victims. According to Walking in Daniel’s Shoes by Tom Mauser, Daniel’s father, Harris approached Mauser and mocked him for his glasses, calling him “four eyes.” Harris then shot Mauser in the hand.

In self-defense, Mauser reportedly shoved a chair at Harris. Harris responded by shooting the 15-year-old in the face. According to a website run by Mauser’s family, the families of Columbine shooting victims were later allowed to review some of the police evidence, which included a diagram of the library — and the chair that Mauser had pushed at his killer.

His father has since become a gun control advocate.
