In November, a memorial for the victims of Sandy Hook was opened to the public, not far from the school grounds.
Victims' names were carved into a wall that circled a sycamore tree.
Nelba Marquez-Greene's six-year old daughter, Ana Grace Marquez-Greene, was among the victims.The tragedy spurred an outpouring of demand for tighter gun control.
Yet the death toll from school shootings keeps climbing as debates over gun control continue.
Since the Sandy Hook massacre, there have been 189 shootings on school grounds, claiming some 279 more lives.
