Parents of two children killed in the Newtown school shootings testified today before the state commission charged with reviewing public policy in the wake of the tragedy.

The parents of two little girls, Ana Marquez-Greene and Avielle Richman, told the Sandy Hook Advisory Commission that the state has failed to put the victims and their families at the center of its response.

Nelba Marquez-Greene, Jennifer Hensel and Jeremy Richman said each family should have received a case worker or liaison to help coordinate support and services.

"It is absolutely disheartening after 23 months to hear of an impacted family with unmet needs," Marquez-Greene said. "That is a tragedy and should not be happening."

The parents also showed a video of the girls to remind people of what the commission is all about.

The commission's chairman says they are nearing the completion of their report, which will provide recommendations to the governor and lawmakers.
