"Our son Aaron Alexis has murdered 12 people and wounded several others," Cathleen Alexis says in the statement. "His actions have had a profound and everlasting effect on the families of the victims. I don't know why he did what what he did, and I'll never be able to ask him, why. Aaron is now in a place where he can no longer do harm to anyone, and for that I am glad. To the families of the victims, I am so, so very sorry that this has happened. My heart is broken."
