Sickening footage shows Texas sisters Cookie and Kitty grin as they’re busted for allegedly hacking mom of 5 to death

The young Texas sisters charged with fatally hacking a mother of five to death flashed sickening smiles as police hauled them off in handcuffs, video shows.

Amaya Cookie Diaz, 19, and Kitty Mia Diaz, 21, were taken into custody by officers in Del Rio, a small city near the Mexican border, just hours after cops say they repeatedly stabbed 32-year-old Caroline “Caro” Peña in broad daylight.

Footage taken outside the siblings’ home showed a barefoot Kitty – wearing tight black shorts and a halter top with an illustration of white hands cupping her breasts – grinning briefly at the ground as two officers escorted her into a patrol car around 4 p.m. Thursday.

Her similarly scantily clad younger sister appeared to put on a show for the camera: brazenly flashing her pearly whites and giggling after sarcastically yelling at the man behind the camera, “Stop recording!”
