Two young Texas sisters charged with fatally hacking a mother of five to death flashed sickening smiles as police hauled them off in handcuffs, video shows.

Amaya Cookie Diaz, 19, and Kitty Mia Diaz, 21, were taken into custody by officers in Del Rio, a small city near the Mexican border, just hours after cops say they repeatedly stabbed 32-year-old Caroline “Caro” Peña in broad daylight.

Footage taken outside the siblings’ home showed a barefoot Kitty — wearing tight black shorts and a halter top with an illustration of white hands cupping her breasts — grinning briefly at the ground as two officers escorted her into a patrol car around 4 p.m. Thursday.

Her similarly scantily clad younger sister appeared to put on a show for the camera, brazenly flashing her pearly whites and giggling after sarcastically yelling at the man behind the camera, “Stop recording!”

A third woman, Kyandra Renee Faz, 21, was also arrested for the grisly murder, according to the Del Rio Police Department, which has not publicly revealed a motive.

Michael Elizondo, an independent journalist in Del Rio, told The Post on Sunday that he rushed to the Diazes’ home after hearing from a friend that there was police activity in the area — and began filming without realizing what the young women were being arrested for. 

“I didn’t know what was going on, but I knew it must be serious” based on the at least five police cars parked outside the house, said Elizondo, 44. 

“I saw the first girl going into the car, and I thought, ‘Whatever.’ … But the second one caught my eye. 

“That girl was in a happy mood. … She was all smiling, goofing off like nothing happened,” he said. 

After Amaya was put in the police cruiser, “All of the sudden I see the window go down, and the girl was sticking out her face, sticking out her tongue and goofing off,” Elizondo said. 

A neighbor in the area later told the journo that they’d seen the sisters “driving recklessly” down the road earlier in the day, he said. 

Footage reportedly shows a bloody Peña facing down her three attackers outside a Sonic drive-through before she died.

She succumbed to her injuries at a hospital in San Antonio around 9 p.m. 

Cops were called to the medical center and tracked the site of the savage attack to an address in Del Rio, which is home to roughly 35,000 residents.

The sisters and Faz were each charged with murder and transported to a local jail, according to the Del Rio Police Department. The department did not respond to Post inquiries.

Kitty’s social media show she is the mother of a young son.

“My son is about to be 4 years old and still a only child,” she captioned a TikTok clip showing the boy earlier this month.
