The arrest video has been watched by hundreds of thousands of people for one reason: the expressions on the faces of Amaya “Cookie” Diaz and her sister Kitty. On the afternoon of June 25 2026 the two sisters and their friend Kyandra Renee Faz were taken into custody in Del Rio hours after 32-year-old Caroline Peña was stabbed to death in broad daylight. Cookie, 19, is seen smiling as officers walk her to a patrol car. Kitty, 21, grins, sticks out her tongue, and appears to goof off while a bystander records. Police and local journalists have described the demeanor as completely out of place for the gravity of the charges.

Court documents name Cookie as the person who used the knife. Peña, a mother of five, was stabbed multiple times near a busy intersection, driven to the hospital by a relative, and later pronounced ᴅᴇᴀᴅ in San Antonio. Investigators have confirmed the three women knew the victim and that an argument preceded the attack. The $5 million bonds and the first-degree murder charges followed quickly. The smiles in the footage have become the central image of the case because they appear so disconnected from the reality of a mother of five lying fatally wounded a short distance away. People who have seen the video repeatedly ask the same question the officers themselves seemed to register in real time: how does anyone look like that after something this irreversible.

Caroline Peña made the same call she made every morning. On June 25 2026 her best friend did not answer. Later that day the 32-year-old mother of five was stabbed multiple times on a public street in Del Rio and died in a San Antonio hospital. The friend has spoken about the unanswered call with a level of pain that has resonated widely. She has said the moment replays constantly and that she believes she could have been present if she had picked up.

Three women who knew Peña—Amaya “Cookie” Diaz, 19, Kitty Mia Diaz, 21, and Kyandra Renee Faz, 21—were arrested hours after the attack and charged with murder. Court records name Cookie as the person who used the knife. Friends have described Peña as a devoted mother whose five children included two with special needs and as someone who routinely put others first. The personal regret expressed by her closest friend has become one of the most emotionally charged elements of the story, sitting alongside the viral arrest footage of the suspects smiling and the rapid legal developments that followed. The combination of a private “what if” and a very public crime has left many who followed the case carrying a similar unsettled feeling.
