Shameless final act of smiling sisters 'Cookie' and 'Kitty' before they were arrested for shocking knife attack on doting mother

By MARYANN MARTINEZ, US TEXAS BUREAU CHIEF Published: 22:16, 30 June 2026 | Updated: 22:26, 30 June 2026 The two sisters who allegedly stabbed of a beloved mother of five to death in a brazen daylight attack quickly got changed and showered after the horrific killing, authorities have revealed.  Caroline 'Caro' Pena, 32, died on Thursday after she was stabbed multiple times in an attack by three women in Del Rio, Texas.  Kitty Mia Diaz, 21, her sister, Amaya 'Cookie' Diaz, 19, and their friend, Kyandra Renee Faz, 21, were arrested on Thursday in the border town- about two hours outside of San Antonio. Each of the three woman have been charged with murder in Pena's death and are likely to remain in jail as each has a $5 million bond, according to criminal complaints obtained by the Daily Mail.  Knowing police were likely on their way, Kitty and Amaya decided to shower after the bloody assault and glam up.  'While speaking with Kitty and Amaya, it was observed that they were no longer wearing the clothing originally seen on the video footage, and they had recently showered, as their hair was wet,' police claimed in the complaint, referencing footage that captured the assault on Pena.  Footage of the trio's arrest showed the smiling suspects in their new outfits.   Kitty changed out of the pink top and blue jeans she was seen wearing in video of the attack into a revealing black romper with a print of hands cupping her breasts on it.  Caroline Pena was stabbed to death on Thursday in broad daylight. She leaves behind her five children Kitty Mia Diaz (left), 21, and Amaya Cookie Diaz (right), 19 have both been arrested Amaya smiled and smirked as she was led away by police in a different outfit as well. While the reason Pena met up with her attackers at a home on the 800 block of E. 10th Street remains unclear, the victim's uncle has revealed that the women all knew each other.  'It's a small town. I knew one of their uncles. Their family, everyone has a connection, so it's even harder. I worked with (the uncle) 30 years. They were close to us. What can you do,' the unnamed uncle said in a phone interview with the Daily Mail from Del Rio.   The uncle did not speculate on the motive behind the attack, however, police revealed the whole confrontation and killing was captured on video from cameras at Faz's house.  'Carolina was observed arriving at Kyandra’s residence and exiting a black Dodge pickup truck,' the criminal complaint stated.  'Shortly after, a black Chrysler 300 arrives on scene, to which Amaya and Kitty exit and confront Carolina. Within the video footage, Amaya is observed exiting the front passenger seat of the vehicle and approaching Carolina.' Amaya- who smirked and smiled as she was being arrested- arrived with a knife in her hand, police alleged.  'Within the video footage, Amaya is observed with an object believed to be a knife in her right hand. Amaya and Carolina get into an altercation, and Amaya is observed striking Carolina in the back, where blood can be observed on the back of her shirt,' the complaint reads. Kitty and Faz later joined in in allegedly assaulting Pena. After that, all four women separated and left.  Another woman, Kyandra Renee Faz, 21, was also arrested in connection with the fatal stabbing Pena’s devastated friend said she would drop anything to help others, even when she had five children of her own to take care of A photograph taken of the women after the attack was posted on a local Facebook page before later being removed.  The image shows Pena's white top covered in blood.  Zelina Ochoa, the victim's friend, said the image was especially difficult to process because she believes it illustrated the imbalance between the alleged attackers and the victim. 'It's a very powerful picture because it shows, you know, these three girls showed up with their weapons and Caro showed up with nothing but her hands,' Ochoa said. Pena went to a local hospital before she was taken to a hospital in San Antonio due to the severity of her wounds.  Her family spent Tuesday making funeral plans for her while caring for her kids ages 3-16.  'Her kids are the ones that are taking it the hardest,' Pena's uncle told the Daily Mail. 'The youngest one, she was going on three.' Two of Pena's kids are autistic. They're being cared for my relatives in the wake of their mom's death.  The comments below have not been moderated.
