The mother of Georgia school shooting suspect Colt Gray apologized to the victims’ families in an open letter — all while insisting her son “is not a monster.”

“To the parents and families of those affected by the tragic events at Apalachee High School, I want to say that I am so sorry from the bottom of my heart,” Marcee Gray, the mother of Colt Gray, wrote in the letter which she provided to CNN.

“If I could take the place of Mason and Christian, I would without a second thought,” she said, referring to the two 14-year-olds killed in the mass shooting. She later added that her “heart breaks for the 2 teachers who gave their lives while in the service of teaching and protecting our children.”

The mother continued: “We are all in a living nightmare right now, and I will personally never forgive myself for what has happened.”

“My son Colt is not a monster. He is my oldest baby. He is quiet, thoughtful, caring, funny, and extremely intelligent. Please pray for him and the rest of our family, as I am praying for all of you every moment of every day,” she wrote.

Her letter comes one week after the teen allegedly carried out the shooting that left two teachers and two students at Apalachee High School dead.

Seven others at the Winder, Georgia school were wounded by gunshots and two others suffered other injuries in the attack, officials said.
