A Ridgefield High School student is being credited with starting Friday's national walkout movement for stricter gun control.

Friday marked 19 years since the Columbine High School shooting, prompting the second round of walkouts at schools across the country.

Ridgefield sophomore Lane Murdock says not enough has been done to stop gun violence since the Colorado shooting. On the night of this year's shooting in Parkland, Florida, she started a petition calling for the day's walkout.

The petition is addressed to the United States Senate and President Donald Trump. "We are the students, we are the victims, we are the change," it reads. The petition has gained more than 265,000 signatures.

More than 2,500 schools nationwide joined Ridgefield High in the walkout. Shortly after 10 a.m., a few hundred students poured onto the football field, many of them covered in blankets due to the chilly weather and holding signs that demanded gun reform.

A moment of silence was held for the 13 Columbine victims. Several speeches followed, including from Sen. Richard Blumenthal and Murdock.

"I really want to make sure that this young generation feels proud of themselves," Murdock said. "But more so, we keep with this momentum. This is not the finale of the youth movement, it's a launch pad."

Both students and Blumenthal stressed the power of voting. They say they're confident that voting is a means to getting the change they've been demanding.
