Overview
- The assault occurred on Thursday, June 25, when Caroline “Caro” Peña was stabbed on East 10th Street in Del Rio and later died at a San Antonio trauma hospital.
- Del Rio police used surveillance video, witness interviews and physical evidence to identify and arrest Kitty Mia Diaz, 21, Amaya Cookie Diaz, 19, and Kyandra Renee Faz, 21.
- A probable‑cause affidavit and footage allege Amaya Cookie Diaz exited a vehicle holding an object believed to be a knife and struck Peña in the back while the other two women joined the attack.
- All three women are charged with first‑degree murder, each placed on a $5 million bond, and prosecutors say the probe remains active with the possibility of additional charges.
- The killing has prompted local mourning for Peña, a mother of five, and a GoFundMe has been started to help her children while the community awaits further details on motive and next court steps.
