Missed call ties Texas sisters’ alleged murder of mom of five

Caroline Peña, a 32-year-old mom of five, was hacked to death in Del Rio, Texas, allegedly by sisters Kitty and Amaya Diaz; Peña had just tried calling her best friend minutes before the attack, who says she’d have been there if she’d answered; the Diaz sisters and a friend were arrested and charged with murder, and video shows one sister grinning as she’s escorted away, while motive has not yet been released.
