Maria Alejandra Lafuente Caso, is accused of killing her husband and dismembering his body

A psychologist who is accused of decapitating her abusive husband before scattering his remains across Mexico City allegedly sent text messages from his phone so friends and family would think he was still alive.

Maria Alejandra Lafuente Caso, 40, who claims she had been repeatedly beaten by her husband Allan Carrera Cuellar, 41, drugged him by slipping sleeping pills into his drink at their home in the Mexican capital.

Prosecutors allege she then took his chainsaw to dismember his body and wrapped his remains in several black bags, before disposing of them across the city.
