The shoes, which came from family members of victims, celebrities and citizens across the country, were placed early Tuesday morning and are expected to stay until late afternoon, the group said.
Almost 15,000 empty shoes were laid on the grass outside of the U.S. Capitol Tuesday - a memorial for all the children who've died by gun violence in the United States in the last five years.
'I'll be traveling to DC literally wearing my son Daniel's shoes, the ones he wore the day he died at Columbine, ' Mauser said in a press release before the event.
Organizers of the memorial said the Parkland shooting was the catalyst for creating the memorial. Her daughter survived the shooting.
The event was planned by Avaaz, an global advocacy group, that has done similar events before. She said open access to weapons is "giving power to trembling hands". The symbolic shoe demonstrations likely draw inspiration from the renowned memorial at the Hungarian Parliament in Budapest that honors lives lost during the Holocaust.
- Thousands of empty pairs of shoes representing children killed by gun violence were lined up outside of the U.S. Capitol on Tuesday as part of a memorial display.
The demonstration was genuine and took place on 13 March 2018.
On Wednesday, students will again take center stage in the political theater over guns that has gripped the country since the February 14 shooting at Marjory Stoneman Douglas High School in Parkland, Florida.
