DEL RIO, TEXAS – The latest revelations from the probable cause affidavit released by the Del Rio Police Department are sparking a profound wave of public outrage and horror across the United States. Far beyond the brutal physical violence that claimed the life of 32-year-old Caroline “Caro” Peña, biological sisters Kitty Mia Diaz (21) and Amaya “Cookie” Diaz (19) appeared to have forged an unprecedented level of calculated arrogance to confront the American justice system.

Police documents expose a chilling reality: after launching a knife attack that collapsed the mother of five, the sister-duo calmly drove home, initiated a process to erase physical evidence, showered, slipped into tight, provocative clothing, and casually “performed” radiant smiles mimicking movie stars the exact moment handcuffs clamped around their wrists. This highly unusual behavior reveals a supreme contempt for the law—a calculated script designed to mock public decency and challenge the legal process.

1. The Anatomy of the Ambush and Irrefutable Video Evidence

According to the sworn probable cause affidavit filed by detectives, the violent encounter unfolded at a residence on East 10th Street in the border city of Del Rio. A residential surveillance video capturing the entirety of the clash has become the state’s anchor evidence, laying bare the savagery of the three co-defendants: the Diaz sisters and their friend, Kyandra Renee Faz (21).

The footage shows Caroline Peña arriving at Faz’s home in a black pickup truck. Suspect Faz later told investigators that Peña had traveled to her residence “looking to start a fight.” However, almost immediately after the interaction commenced, a black Chrysler belonging to the Diaz sisters pulled up to the curb. Kitty and Amaya “Cookie” Diaz exited the vehicle and aggressively closed the distance, confronting Peña directly.

The ruthlessness escalated to a maximum peak when the camera captured the exact moment 19-year-old Amaya “Cookie” Diaz stepped out of the Chrysler and approached the victim “with an object believed to be a knife in her right hand.” The affidavit explicitly notes:

“Amaya Diaz and the victim got into an altercation, and Amaya Diaz is seen striking Peña ‘in the back, where blood can be observed on the back of her shirt.’”

Instead of halting after the blade struck, older sister Kitty Mia Diaz instantly joined the fray, “physically assaulting” Caroline, while Faz swarmed in to participate in the group beating. Once the bloody assault was eventually broken up by bystanders, the suspects coldly returned to their Chrysler and sped away from the area, leaving the 32-year-old mother fading rapidly on the grass. Caroline Peña was rushed to the Val Verde Regional Medical Center, but due to the deep penetration of her internal trauma, she did not survive to return home to her five young children.

2. Erasing the Traits of Crime: Showering and Laundering Evidence

What deeply disturbed veteran investigators of the Del Rio Police Department was the scene discovered at the Diaz residence less than two hours after the homicide. When officers descended upon the home—where Kitty Diaz’s young child was also present—the two sisters exhibited absolutely no signs of panic, panic-buying, or attempts to flee the jurisdiction.

Instead, they had already executed a methodical “cleanup” procedure with complete composure:

• Destruction of Physical Evidence: During a search of the property, officers discovered that the exact clothing Kitty Diaz was observed wearing in the surveillance grid had been stripped off and placed inside a washing machine, which was actively running to purge the victim’s bloodstains.
• Showering and Wardrobe Selection: By the time officers crossed the threshold with arrest warrants, both Kitty and Cookie Diaz had completely showered. They had systematically scrubbed away the street dust, sweat, and biological traces of the assault from their skin. Rather than appearing in the disheveled state typical of fleeing suspects, the two young women chose to don tight, provocative, and neatly arranged outfits, as if preparing for a night out or a fashion shoot.

From a forensic psychology standpoint, this immediate grooming process was far more than an attempt to delete biological data; it was a deliberate preparation of public image. The Diaz sisters fully anticipated the police response, and they fundamentally refused to be paraded before the community or media lenses looking haggard or defeated. They sought to project a persona of untouchable defiance and toxic glamor.

3. The Movie-Star Smirks Challenging Justice Behind Patrol Car Glass

The sisters’ meticulous aesthetic preparation effectively transformed law enforcement’s transport process into a public stage for juvenile arrogance. Escorted out in handcuffs at approximately 4:00 p.m. before a growing crowd of local journalists and residents, Amaya “Cookie” Diaz and Kitty Mia Diaz refused to bow their heads, shield their faces, or evade the lenses.

Instead, they repeatedly flashed wide, radiant, confident smiles directly at the cameras, mimicking the red-carpet demeanor of Hollywood celebrities. Even more disturbing, once secured in the rear passenger bench of the police cruiser, the two young women pressed their faces against the glass window, stuck their tongues out, and smirked to mock the journalists recording them. The utter detachment from the reality that a mother of five was actively dying in a trauma ward, juxtaposed against their newly changed glamour clothing, created a grotesque sequence that sent shockwaves across the country.

This was entirely a scripted posture. Raised within a hyper-toxic digital culture where infamy is frequently chased with greater fervor than standard fame, these young offenders viewed their arrest not as a mark of lifelong shame, but as a twisted moment of viral spotlight. The smirks and gestures sent an explicit message of mockery to both the judicial system and the victim’s family: “We are not afraid, and we control the narrative.” Their laughter stood as a direct insult to five children who had just lost their mother, exposing a total moral bankruptcy.

4. The Catastrophic Price of Arrogance: A Historic $15 Million Total Bail

However, the Diaz sisters’ script for confronting justice immediately collided with the unyielding severity of the Texas magistrate. The county judge, after reviewing the surveillance footage and receiving logs detailing the defendants’ total lack of remorse, running washing machines, and mocking behavior during the arrest, handed down a crushing financial penalty.

Bail was set at an unprecedented $5 million for each individual suspect, totaling a historic $15 million bond for the trio. This massive financial barrier represents one of the highest bonds ever levied against teenage and young adult homicide suspects in Val Verde County. This aggressive judicial measure effectively shattered the sisters’ illusion of untouchability. Lacking the financial liquidity to secure such an astronomical sum, the young women were forced to end their public “performance” and face the grim reality of standard detention within the steel walls of the GEO Corrections Facility.

5. Conclusion

The stabbing of Caroline Peña remains an active, ongoing investigation, and the Del Rio Police Department notes that additional charges may still be filed as final autopsy parameters mature. Beyond the violent logistics of the street encounter, the details of the active washing machine, the provocative change of clothes, and the movie-star smiles will remain a chilling testament to modern youth pathology.

The brief script of arrogance engineered by the 19 and 21-year-old suspects secured them a few seconds of defiance before media lenses. Yet, as the initial adrenaline fully depletes, they are left to confront the highest brackets of the Texas Penal Code—where first-degree murder carries a maximum penalty of life imprisonment without the possibility of parole or the death penalty. The ultimate verdict of the court will stand as the definitive response to those cold-blooded smiles, rightfully restoring justice to Caroline “Caro” Peña and her five orphaned children.
