VIDEO “STOP FILMING!”: As Amaya “Cookie” Diaz was being led away in handcuffs, the camera captured her smiling and shouting, “Stop filming!”. The footage horrified many—but investigators have yet to explain what allegedly motivated the attack on Caroline Peña
In the hours following the fatal stabbing of 32-year-old Caroline “Caro” Peña in Del Rio, Texas, on June 25, 2026, one piece of footage has dominated public attention and fueled widespread outrage. As 19-year-old Amaya “Cookie” Diaz was escorted in handcuffs to a patrol vehicle alongside her sister Kitty Mia Diaz, citizen video captured her smiling, appearing lighthearted, and directing a command at those filming: “Stop filming!” or “Stop recording!” The short clip, which also showed similar grinning behavior from the group, quickly spread across social media and news outlets, horrifying viewers who contrasted the suspects’ demeanor with the gravity of the alleged crime.
While the arrest video has become a focal point of public anger, investigators from the Del Rio Police Department have not yet publicly detailed a clear motive for the broad-daylight attack that claimed Peña’s life. The lack of transparency on the “why” behind the confrontation—combined with the shocking visuals—has left the community and national audiences demanding answers as the case moves forward in the justice system.
The Attack and Rapid Arrests
Caroline Peña, a mother of five known for her warmth, resilience, and dedication to her family, was stabbed multiple times in the 800 block of East 10th Street near a busy Sonic drive-thru around 2 p.m. She was transported to Val Verde Regional Medical Center by her nephew, arrived talking despite her injuries, but was later airlifted to San Antonio, where she died around 9 p.m. from wounds that included a punctured lung.
Del Rio police responded swiftly. Using surveillance footage from the scene, physical evidence, and numerous witness interviews, detectives identified three suspects within hours: sisters Kitty Mia Diaz (21) and Amaya “Cookie” Diaz (19), and their friend Kyandra Renee Faz (21). The women were arrested starting around 4 p.m. that same day without incident. Following Peña’s death, all three were charged with murder and held on high bonds.

Surveillance video reportedly shows Peña’s black Dodge pickup arriving at a residence, followed by the suspects’ vehicle. Peña stepped out, and the confrontation escalated quickly, with Amaya “Cookie” Diaz allegedly wielding the knife in the initial strike to Peña’s back. Witnesses described the violence erupting rapidly in a public area.
The Arrest Video That Sparked Outrage
The now-viral citizen footage, recorded as officers led the Diaz sisters from a home, captured moments that many found deeply disturbing. Amaya “Cookie” Diaz is seen smiling toward the camera, with reports describing giggling and a casual attitude. She issues the “Stop filming!” remark, which some interpreted as an attempt to control the narrative or a brazen disregard for the situation. Similar smiles were noted in related arrest imagery and mug shots.
The video’s impact was immediate and visceral. In the context of a mother of five being allegedly stabbed to death in broad daylight, the apparent levity horrified viewers nationwide. Social media platforms filled with condemnation, with users calling the behavior “sickening,” “callous,” and emblematic of a lack of remorse. News coverage amplified the footage, turning it into a symbol of the case’s emotional weight. Independent journalists and local outlets like KENS 5 contributed to its dissemination.
Peña’s friends and family expressed additional pain. Zelina Ochoa and Christina Salinas, who shared heartfelt tributes highlighting Peña’s role as a devoted mother and loyal friend, faced the added trauma of seeing the suspects’ demeanor juxtaposed against their loss. Salinas, who missed a call from Peña shortly before the incident, described the permanent void: “It’s like a part of me got ripped out.”
The Unanswered Question: Motive
Despite the speed of the arrests and charges, investigators have not publicly released a definitive motive. Court documents and police statements reference the sequence of events but stop short of explaining what prompted Peña to the location or what triggered the alleged attack. One reported detail suggested a claim that Peña arrived “looking to start a fight,” but this remains unconfirmed publicly and is disputed by descriptions of Peña as someone who avoided drama and promoted peace.
The absence of a clear motive has intensified public frustration. Many wonder about any prior connections between Peña and the suspects, possible disputes, or other circumstances that led to the deadly confrontation. Surveillance footage from the critical first moments—Peña stepping out of her car and the immediate approach— is expected to play a key role in court, but full details have not been disclosed.
This information vacuum, paired with the arrest video, has led to widespread speculation and anger. Community members and online commentators have questioned accountability, the handling of the case, and broader issues of youth violence in the border town. The fact that the attack occurred in broad daylight at a busy intersection, with witnesses present, adds to the sense of disbelief.
Peña’s Legacy and Community Response
Amid the focus on the suspects’ behavior, friends emphasize remembering Caroline Peña for how she lived. Born in 1993, she was a twin who became a teen mother and built a life centered on her children. She participated in support programs for young parents, helped friends generously, and was described as someone with an “infectious laugh” and a fighter’s spirit. Her five children, including two with special needs, were her world.
A GoFundMe established to support the family gained traction quickly. Private funeral arrangements were entrusted to a local home, and tributes highlighted her role as “the village” for others. Ochoa recalled Peña standing her ground during the attack: “She didn’t show up there thinking that today is my last day.”
The case has shaken Del Rio, prompting discussions on safety, bystander response, and the long-term effects on children who lose a parent to violence. Salinas shared Ring camera footage of happier times, underscoring the personal loss beyond the headlines.
Legal Proceedings and Lingering Questions
The three suspects remain in custody pending further court appearances. They requested court-appointed attorneys during initial proceedings. The high bonds reflect the severity of the first-degree murder charges. Police have indicated the investigation is active, with the possibility of additional charges or evidence.
For many following the case, the “Stop filming!” video represents more than an unfortunate moment—it symbolizes a perceived disconnect from the human cost of the alleged crime. The continued lack of a public motive explanation has only heightened calls for transparency and justice. As the legal process unfolds, Peña’s loved ones hope for answers that honor her memory and provide closure for her children.
The footage may have horrified the public, but the real story remains the life cut short and the family left behind. Investigators’ eventual explanation of events—including any motive—will be closely watched in the weeks and months ahead.
