One Sister Is Free, the Other Remains in Jail: The Latest Twist in the Caro Peña Murder Case

The criminal case involving the death of Caroline “Caro” Peña has taken another turn after Amaya “Cookie” Diaz, 19, secured release from jail while awaiting trial. Her family reportedly paid $200,000 through a bonding arrangement to obtain her release under a $2 million bond. The development has drawn renewed attention because Cookie is one of three women charged in connection with the death of the 32-year-old Texas mother of five. Although she is now outside custody, the criminal proceedings against her remain active, and the allegations have not been resolved in court.

Cookie’s sister, Kitty Mia Diaz, 21, and their friend Kyandra Renee Faz, 21, are accused alongside her in the June 25, 2026, incident in Del Rio. According to investigators, Peña arrived at a residence before a confrontation developed involving the three defendants. Police allege that Cookie was responsible for the stabbing, while Kitty and Faz allegedly joined the ᴀssault. Surveillance footage reportedly helped investigators reconstruct the sequence of events. Peña was transported for medical treatment but died later that evening at a hospital in San Antonio, leaving five children and other relatives to cope with her sudden death.

The three defendants have not experienced the same path through the legal system. Cookie has been released under bond conditions, but Kitty remains in custody despite an earlier reduction in her bond amount. Faz is being held on a higher bond of $5.2 million and has entered a not-guilty plea, according to published accounts. Cookie is scheduled to appear for arraignment on November 4, while Faz’s next pretrial hearing is set for December 11. These different custody arrangements reflect separate decisions within the ongoing proceedings and do not determine the eventual outcome of the charges.

The circumstances behind the alleged attack remain a central issue. Police have not publicly established a definitive motive, and the precise nature of the relationships among the women and Peña has not been fully explained in public accounts. The case received additional attention after images and footage from the arrests circulated online, prompting discussion beyond Del Rio. However, public reactions cannot subsтιтute for evidence presented in court. As the case advances, investigators’ findings, witness testimony and legal arguments will be essential to establishing what happened and determining the responsibility, if any, of each defendant.
