Santa Barbara, May 28 (RHC)-- Thousands of people gathered at the University of California-Santa Barbara yesterday during a day of mourning for the victims of last Friday’s shooting and stabbing rampage.

Elliot Rodger killed six people and then himself after posting a video online saying he was seeking revenge against all women for rejecting his sexual advances. University of California-Santa Barbara students joined together to remember their classmates.

The shooter in the University of California, Santa Barbara, killings had three semiautomatic handguns, all purchased legally. The father of one of the slain victims is now vowing to continue speaking out in favor of gun control.

Richard Martinez, whose 20-year-old son Christopher was killed, made headlines immediately following the attack after calling out the National Rifle Association and politicians who stand in the way of gun reform. He says he rejects condolences from lawmakers, saying that they should get to work "and do something." And Martinez called on all Americans to send a postcard to Congress demanding the passage of gun reform laws.

According to the Gun Violence Archive, firearms have killed more than 4,100 people in the United States since January 1st of this year.
