A heroic Florida mom died protecting her children by sending her son to a neighbor to call 911 after her husband flew into a rage over an NFL game and shot her daughter in the face.

Jason Kenney, 47, gunned down his wife, Crystal Roure, 38, just days before Christmas, after she asked him to turn off the San Francisco 49ers versus Indianapolis Colts game, USA Today reported.

Kenney had “been drinking during the evening” on Dec. 22 as he watched his favorite team, the 49ers, beat the Colts. When Roure told him that “she did not want to watch football” anymore, Kenney became incensed, the Polk County Sheriff’s Office said in a statement.

At around 11 p.m., “the argument got really heated,” and Roure told her son, 12, to go to a neighbor and call 911, Sheriff Grady Judd told reporters.

Roure’s sister believes this simple act saved the lives of the children.

“My sister died a hero for protecting her children and getting my nephew out of the house to make the 911 call. She did that. She saved their lives and by doing so my nephew saved his sister’s life, and thank God the baby was untouched,” Stephanie Roure told USA Today.

As the boy was leaving the Lakeland home, he heard a gunshot, Grady said.

Deputies were called to the house and found Roure’s lifeless body, along with her critically wounded daughter, 13, deputies said.

Kenney had shot the teen, his stepdaughter, in the face. Miraculously, she survived, with the bullet striking her nose and ricocheting through the top of her head, USA Today reported.

The couple’s baby girl, their only child together, was asleep unharmed in her crib, deputies said.

Kenney fled to his late father’s home nearby before calling his sister in Upstate New York, and telling her, “I’ve done something very, very bad, very bad,” Sheriff Judd said.

“You’ll see me on the news, but I am not going to jail. I’m not going to jail for the rest of my life,” he told his sister.

When deputies tracked Kenney down to his late father’s home, they heard a single gunshot come from the shed.

Roure, who had two older children from a previous relationship, had married Kenney two years earlier after meeting him at church.

He was reportedly violent and had struggles with drugs and alcohol, deputies said.

“You know you’re drinking, you’re using cocaine again. This is not the way the family should be. You need God,” Roure wrote in an undated note to her husband that was reportedly found at the couple’s house, and quoted by deputies.

“After they were married, I know she said he was drinking a lot mor,e but she said that he was going to stop and said he would get help with it. Obviously, that didn’t happen,” Roure’s sister, Stephanie Roure, told USA Today.

Kenney had no prior criminal record, according to Judd.

“He absolutely destroyed a family,” the sheriff said.

“When you go in there, there is a beautiful Christmas tree with lots of Christmas presents under the tree, just like the nuclear family should be … and it ends up this way,” Judd said.

The three children are currently living with their grandparents as the family comes to terms with the horrific murder-suicide.

“With heavy hearts, we share the heartbreaking loss of Crystal, a loving and devoted mother whose life was stolen far too soon,” a GoFundMe set up by the family read.

“What has happened to this beautiful family is a tragedy and it is unimaginable. We cannot wrap our hearts and minds around it,” the fundraiser reads.
