LITTLETON, Colo. -- Some parents of Columbine High School shooting victims plan to join students in Littleton who plan to walk out of schools on Wednesday to protest gun violence.
About two blocks from Heritage High School, Tom Mauser, who lost his son Daniel nearly two decades ago, will meet with students along with other parents of Columbine victims.
Mauser has been an advocate for gun violence legislation nationwide after losing his 15-year-old son Daniel in the Columbine massacre on April 20, 1999.
Mauser is an advocate for Colorado Ceasefire, which has been seeking gun legislation since 2000.
The group has worked to enact Colorado firearms laws such as universal background checks and bans on high-capacity magazines.
Mauser and several other parents who lost their children at Columbine will speak to Heritage High School students as they leave for 17 minutes to honor the victims of the Parkland, Florida, shooting.
