Accused Georgia school shooter apologized to his mom before allegedly killing four, anguished grandfather reveals

FITZGERALD, Ga. — Accused Georgia school shooter Colt Gray apologized to his mom before he allegedly killed four people — prompting her to make a desperate call in a bid to stop the tragedy, according to his grandfather and a report.

Charles Polhamus said his daughter Marcee Gray was visiting him at his home in Fitzgerald, Georgia, when Colt sent her a haunting text Wednesday morning.

“I’m sorry, mom,” the message read.

Marcee called Apalachee High School and warned a counselor of an “extreme emergency,” a relative told The Washington Post.

“I was the one that notified the school counselor at the high school. I told them it was an extreme emergency and for them to go immediately and find [my son] to check on him,” she told her sister, according to the outlet.

After getting Colt’s text, Marcee rushed into her car to head to Winder, about three hours away, and heard half way there that two students and two teachers were killed, Polhamus, 81, told The Post in an exclusive interview Saturday.

Marcee Gray could not be reached Saturday.

Polhamus slammed Colt’s dad Colin as “evil” and claimed Colin Gray got Marcee addicted to drugs — and ruined the family, setting the stage for the violence at Apalachee High School that left two students and two teachers dead.

“Collie Gray did this to his family and he will rot in hell for it. That’s a fact,” Polhamus said outside his home. “He needs the death penalty. He is probably one of the worst narcissists in the world.”

Both Colt and Colin, 54, face charges of murder in connection to the cold-blooded shooting. Colin allegedly gave his son the AR-15-style rifle used in the massacre as a Christmas gift.

Although the former marine doesn’t excuse the violence, he said Colt was driven to it because of his parents’ — namely his father’s — bad behavior.

“He was a good kid turned bad in a bad situation. It’s sad. An environment that a kid grows up in has everything to do with their personality and what they become,” Polhamus said.

Colin regularly screamed at Marcee and the kids, he claimed.

Polhamus accused Colin of becoming addicted to opiates a few years ago, after hurting his back.

“Living in that environment – they lost their house, he lost his job,” the grandfather said.

“Two years he laid on his back and never did a thing. My daughter Marcee worked. They had a half-million dollar farm before all this happened and they lost it.”

Marcee — whose rap sheet stretches back nearly two decades — left Colin a few years ago and moved with her three kids to Polhamus’ home, he said, but police sent the children back to their father after she was caught with drugs.

Her dad denied reports from former neighbors of the family that Marcee abused the kids herself and locked them out of the house.

“Colt is like a lot of young kids these days with the tablets and some of the garbage they pull up, the blood and all the fighting. If you don’t think that has an impact on young kids, you’re missing the boat, and that was also part of Colt’s problem.”
