A man touches the snow covered grave of six-year-old Ana Grace Marquez-Greene, one of 20 schoolchildren killed in the December 14 shootings at Sandy Hook Elementary School, at the Newtown Village Cemetery Newtown, Connecticut on Christmas morning December 25, 2012.
Six-year-old girl Ana Marquez-Greene was one of 20 children killed in the Dec. 14 shooting.
"I want to live in a better America ... one where our leaders are working collaboratively for the good of the people and the protection of children. Please! No more! Ya basta! (Enough is enough!)" wrote her grieving mother, Nelba Marquez-Greene, in a post to her 39,000-plus Facebook followers.
Hundreds of thousands of Americans signed a petition calling for tougher gun controls in the wake of the shooting, leading President Barack Obama to open a task force. Other petitions -- signed by tens of thousands -- support the NRA's call to arm schools.
"No lockdown procedure in the world could have stopped someone with that kind of power and ammunition," Marquez-Greene wrote. "His guns had enough power and ammunition to kill a lot more children. A lot more children!"
Six adults were also killed in the shooting.
On the day of the shooting, Marquez-Greene wrote she had just bought her youngest child's Christmas present: a Kindle Fire HD e-reader.
The family lived in Winnipeg for about three years before moving to Newtown in the summer. Nelba worked at the University of Winnipeg's Aurora Family Therapy Centre, while Ana's father Jimmy was a music professor at the University of Manitoba.
