Smiling Sisters S.t.a.b Mom of Five to D.e.a.t.h in Broad Daylight — Police Drop Shocking New Theory That Changes Everything
In the small border city of Del Rio, Texas, a brutal stabbing on a busy street in broad daylight has left a community reeling and raised disturbing questions about violence among people who knew one another. On June 25, 2026, 32-year-old Caroline “Caro” Peña, a devoted mother of five, was fatally stabbed in what authorities describe as a targeted confrontation rather than a random act of violence.
According to police reports and court documents, Peña arrived at a residence on the 800 block of East 10th Street in her black Dodge pickup truck. Moments later, sisters Kitty Mia Diaz, 21, and Amaya “Cookie” Diaz, 19, along with their 21-year-old friend Kyandra Renee Faz, pulled up in a black Chrysler 300. Surveillance footage from the home reportedly captured the entire sequence. Investigators allege that Cookie exited the vehicle holding an object believed to be a knife and confronted Peña, striking her in the back. Blood was visible on Peña’s shirt as the attack continued, with Kitty and Faz allegedly joining in to assault the victim before all three fled the scene.
Peña, fighting for her life, was driven to a local hospital by her nephew. She was later airlifted to a facility in San Antonio, where she succumbed to her injuries around 9 p.m. that evening, approximately seven hours after the attack. Medical reports indicated she suffered multiple stab wounds, including to the back and stomach area.
What has stunned many is the new information from Del Rio Police Chief Frank Ramirez: the four women knew each other, and Peña had a reason to go to the location where the argument erupted. This revelation suggests the incident stemmed from a personal dispute rather than a chance encounter. The exact motive remains under active investigation, but authorities emphasize that the attack was not random.
Shortly after the stabbing, officers tracked the suspects to another home. When they arrived, the sisters had reportedly changed out of the clothing seen on video — Cookie in a red tank top and blue jeans, Kitty in a pink tank top — and appeared to have recently showered, with wet hair. Clothing linked to the incident was allegedly found in a washing machine. Kitty Diaz faces an additional charge of tampering with evidence.
Body camera footage of the arrests quickly went viral, showing the sisters smiling and laughing as they were taken into custody, an image that many found deeply unsettling given the circumstances. All three women were charged with murder and held on high bonds totaling over $15 million each. They requested court-appointed attorneys during their initial court appearance.
The case has sparked widespread outrage, particularly because Peña was a mother raising five children, including some with special needs. Friends and family remember her as someone who cared deeply for her loved ones. The speed of the arrests — within hours of the attack — highlights the effectiveness of surveillance evidence and quick police work in a public setting.
As the investigation continues, authorities are piecing together the full circumstances of the dispute. This tragic event serves as a stark reminder of how quickly personal conflicts can escalate into irreversible violence, leaving families shattered and a community searching for answers in a case that has gripped national attention.
