Bone-chilling new video captures the moment a former Mexican beauty queen is gunned down in front of her baby — allegedly by her jealous mother-in-law.

Almost more grim is the callous, almost nonchalant reaction by Carolina Flores Gomez’s husband after finding that his mother had allegedly executed his wife and the mother of his child.

The 27-year-old new mom, who was Miss Teen Universe for Baja California in 2017, is seen at home in the wealthy neighborhood of Polanco with her mother-in-law, Erika Herrera, when the tragic shooting took place on April 15, according to the clip obtained by the Spanish-language outlet Reforma.

Gomez, wearing a white-patterned robe, is shown walking in the living room of the luxury pad, where a playpen, a stroller and children’s toys are set up, then walks toward the back of the house with Maria following behind her, according to the footage.

A split second later, a shot rings out in the background, followed by a scream and several more shots.

The victim’s husband, Alejandro Gomez, then walks into the frame holding the couple’s baby.

“What was that?” he asks in Spanish.

“What did you do, crazy?” an unidentified woman’s voice is heard saying.

“Nothing,” Herrera answered. “She made me angry.”

“What’s wrong with you? She’s my family,” the son responds.

“You’re mine and she stole you,” his mother said.

Police in Mexico City have opened an investigation into the shooting but have not announced charges.

They did identify Herrera as the prime suspect — and raised questions about why Gomez and his mother did not report the fatal shooting until the following day.

The dead woman’s mother, Reyna Gomez Molina, told Univision News that Gomez delayed reporting the incident due to concern over the couple’s young baby.

She told the outlet that her son worried that the tot would end up in a foster home.
