Two sisters, 19-year-old Amaya Cookie Diaz and 21-year-old Kitty Mia Diaz, are arrested in Del Rio, Texas, on charges related to the stabbing death of Caroline Peña, 32, a mother of five, police say. Multiple outlets report the sisters were taken into custody after the killing occurred in broad daylight on Thursday. Court and police accounts cited by the reports describe the attack as involving repeated stabbings and characterize it as occurring just hours before officers arrived at the sisters’ home. One report also says the sisters were filmed or photographed while being arrested and that they appeared to be smiling as they were handcuffed. Another outlet cites court documents alleging the sisters attempted to cover up aspects of the incident, including actions such as changing clothes, showering, and tampering with evidence before police contacted them. Additional reporting references social media activity by Kitty Mia Diaz in the days leading up to the killing. The reports consistently state that the sisters face murder charges tied to Peña’s death, and the allegations are attributed to police and court materials.
