In a heartbreaking letter, the parents of a child killed in the Sandy Hook Elementary School shooting in 2012 offer comfort to the families of the Orlando nightclub victims.

Jimmy Greene and Nelba Márquez-Greene lost their 6-year-old daughter, Ana Márquez-Greene, in 2012 when the school was attacked by a mass shooter.

‘I am sorry that our tragedy here in Sandy Hook wasn’t enough to save your loved ones,’ the couple wrote on their Facebook page, Remembering Ana Márquez-Greene.

‘How do I tell my son that fifty people all died the way his sister did? And in one of our favorite places: Orlando, Florida.’

Márquez-Greene founded The Ana Grace Project in memory of her daughter. The project hopes to promote recovery and to raise awareness about gun violence.

‘Don’t you dare even listen to even ONE person who may insinuate that somehow this is your loved ones fault because they were gay or any other reason,’ the couple urged. ‘Nor is it God’s wrath… They did that to us on Sandy Hook – too. And it broke my heart.’

The couple also touched on the hypocrisy of the religious right by saying, ‘I am waiting for the church to be as outraged about gun violence as much as we seem to be about who pees where in a Target bathroom.’

The family then shared that they would try to learn about each of the Orlando victims’ name and story.

‘We will commit as a family to learning about their lives and the legacies you build in their memory… My son will learn about your loved ones. And we will not forget. We will say their names out loud. We will remember your children. As you remembered and learned about ours.’

The couple provided links to The Trevor Project and It Gets Better, and encouraged people to get help if they face bullying.

Greene and Márquez-Greene also urged people to bring up the issue of gun violence in a house of worship or community group, and to work with the police to prevent any form of violence from happening.

‘Let’s be more than bystanders. Let’s save lives,’ they wrote.
