In June 25, 2026, Del Rio police responded to Val Verde Regional Medical Center after a woman arrived with multiple stab wounds. Police responded to Val Verde Regional Medical Center on June 25 following a report that a woman had been admitted with stab wounds, and she was transported to a medical facility in San Antonio, where she died. The victim was later identified as Caroline “Caro” Peña, 32, a mother of five.
Investigators say an altercation had taken place at a residence on East 10th Street before Peña was taken to the hospital. Officers learned that an altercation between the victim and suspects had occurred at a residence on East 10th Street. Within roughly a day, three women were arrested and charged.
Who Has Been Charged
Three people face murder charges in connection with the case: Kitty Mia Diaz, 21; Amaya Cookie Diaz, 19; and Kyandra Renee Faz, 21, were arrested on charges of murder in connection with the fatal attack, according to the Del Rio Police Department. Kitty and Amaya are sisters; Faz is described by police as their friend. Police said the four women all lived in Del Rio, Texas, and the victim knew the three suspects.
According to court filings described by reporters, the allegations were built from surveillance and body-worn footage, witness interviews, and physical evidence. Detectives reviewed surveillance video, processed evidence and interviewed witnesses before identifying the three as suspects. All three have been held on high bail. The three women have each been held on $5 million bail, according to the court filing.
It is important to state plainly: a charge is an accusation, not a finding of guilt. As of publication, no one has been convicted, and it was not clear whether the accused had retained attorneys able to comment on their behalf.
Why the Arrest Footage Went Viral
Part of why this case drew national attention was footage of the arrests, in which the Diaz sisters were seen smiling and appearing unbothered as they were escorted to patrol cars. That imagery spread quickly and drove much of the online reaction. Del Rio Police Chief Frank Ramirez addressed it in a widely cited interview, saying the demeanor struck him as lacking remorse, while stressing that the investigation is ongoing and that early theories can change. Ramirez told TMZ that police are actively investigating and that theories are subject to change.
Readers should treat viral clips cautiously. Demeanor during an arrest is not evidence of guilt, and clips stripped of context routinely fuel misleading conclusions. Courts decide these cases on evidence, not on how someone looked on camera.

What Is Still Unknown
Several key questions remain open. Police have not publicly released a motive. The full sequence of events, the role each defendant allegedly played, and how the case will proceed through indictment and trial are all still to be determined.
Anything circulating beyond what police and court records confirm should be treated as unverified.
The Legal Road Ahead
In Texas, a murder charge moves from arrest to a grand jury, which decides whether to formally indict. If indicted, the case proceeds toward trial, where the prosecution must prove guilt beyond a reasonable doubt.
Bail set at $5 million signals that the court viewed the charges as extremely serious and the defendants as significant flight or safety risks, but bail is not a verdict. Expect the timeline to stretch over many months, with pretrial hearings, evidence disclosure, and possible motions along the way.
How to Follow This Case Responsibly
For accurate updates, rely on primary and established sources rather than aggregators or social clips: the Del Rio Police Department’s official releases, Val Verde County court records, and reporting from outlets such as NBC News, Fox News, and local Texas stations covering Del Rio.
Coverage that names a motive, assigns specific blame, or fills in graphic detail beyond official filings should be read with skepticism until confirmed.
