Three women have been charged with murder following the death of a 32-year-old Texas mother of five after an attack in Del Rio, according to local authorities, as reported by The New York Post.

The Del Rio Police Department said sisters Amaya "Cookie" Diaz, 19, and Kitty Mia Diaz, 21, along with 21-year-old Kyandra Renee Faz, were taken into custody Thursday in connection with the death of Caroline "Caro" Peña.

Police have not publicly disclosed a motive in the case.

The arrests came just hours after investigators say Peña was attacked in broad daylight in Del Rio, a city near the Texas-Mexico border with a population of approximately 35,000.

Video recorded outside the Diaz sisters' residence showed officers escorting the suspects into patrol vehicles following their arrests.

In the footage, Kitty Diaz, who was barefoot and wearing black shorts and a black halter top, briefly smiled while officers walked her to a police cruiser. Her younger sister, Amaya Diaz, was also taken into custody outside the home.

Michael Elizondo, an independent journalist based in Del Rio, said he arrived at the residence after hearing reports of significant police activity in the neighborhood.

"I didn't know what was going on, but I knew it must be serious" because of the number of police vehicles at the scene, Elizondo said.

He said he initially did not realize what the women had been arrested for.

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

Elizondo described the demeanor of one of the suspects as officers completed the arrests.

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

He also recalled another moment after one of the suspects had been placed inside a patrol vehicle.

"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.

According to Elizondo, a nearby resident later told him the sisters had been seen "driving recklessly" through the neighborhood earlier that day.

Authorities have not commented publicly on that account.

Investigators believe the attack occurred outside a Sonic Drive-In restaurant in Del Rio. Video reportedly captured Peña confronting three women before she was critically injured.

Peña was transported to a hospital in San Antonio, where she died at approximately 9 p.m.

Police said officers responding to the hospital traced the incident back to the Del Rio location, where the attack allegedly occurred.

Following their arrests, Amaya Diaz, Kitty Diaz, and Faz were each charged with murder and booked into a local jail, according to the Del Rio Police Department.

The department has not released additional information regarding the investigation and did not respond to media inquiries seeking further comment.

Peña's death has drawn attention throughout the Del Rio community. She is survived by five children.

Social media posts attributed to Kitty Diaz indicate she is the mother of a young son. Earlier this month, she shared a TikTok video featuring the child and wrote, "My son is about to be 4 years old and still a only child."

The murder investigation remains ongoing as authorities continue working to determine the circumstances surrounding the fatal attack.

Police have not announced any additional arrests or released further details about what led to the confrontation.
