The mother of the man who killed 21 people in a school shooting begged for forgiveness in a Friday interview.

I have no words. I don't have anything to say. I don't know what he was thinking, she said from inside her car. Her comments, originally in Spanish, were translated by CNN. Please don't judge him. I want the children who died to forgive me.

The 18-year-old shot his grandmother in the face before driving to Robb Elementary School, barricading himself in a classroom and opening fire. He killed 19 students and two teachers in the deadliest US school shooting in a decade before being killed by police.

The shooter may have gone to the elementary school to get closer to the children because he didn't want to pay attention to the other bad things.

CNN reported that he said, "Forgive me."
