A coward decided to take our eight-year-old son Fletcher away from us.

The horror and the heartbreak of the Minneapolis mass shooting.

It went so fast that I didn't even really know what was happening.

Innocent children, wounded here, physically.

A piece of a bullet's still in my head, but it's too dangerous to take out. And emotionally.

What's making you the saddest right now? My friend died.

From CBS News headquarters in New York, this is the CBS Evening News.

Good evening. I'm John Dickerson.

We now know the names, and we can now show you the faces of the two children killed in the Minneapolis shooting.

Fletcher Merkel was eight years old. Harper Moiseki was 10.

They were attending Wednesday morning Mass, along with nearly 200 other Catholic school children.

At the Church of the Annunciation, when a shooter opened fire through stained glass windows,

another child is in critical condition.

One of the 15 children and three adults wounded.

And the police say it could have been even worse because locked doors kept the shooter from entering the church.

Maurice Dubois is in Minneapolis.

And John, we heard today from Fletcher Merkel's father, Jesse, about his family's unimaginable loss.

Please remember Fletcher, for the person he was and not the act that ended his life.

Give your kids an extra hug and kiss today.

We love you Fletcher.

You will always be with us. Jesse Merkel said the hole in his family's heart will never heal.

The police, meanwhile, said the shooter was obsessed with killing children
