A 45-year-old man, Mamunur Rashid Mamun, has been accused of killing his mother, Anwara Begum, 58, in Baje Durgapur village of Jessore Sadar on Thursday at about 5:30pm. Local residents said Mamun used a sharp boti to sever her head from her body after an argument at their home. He fled after nearby people responded to screams, leaving the weapon behind.

Jessore Kotwali police station officer-in-charge Mamun Khan said investigators suspect Mamun held resentment toward his mother over the breakdown of his two marriages. Locals said he blamed her for the separations and had previously argued with and assaulted her. His two wives reportedly left following marital disputes.

Residents said Mamun had mental health problems and was admitted to Pabna Mental Hospital about three years ago, where he received treatment for two to three months. They also said he returned home on Thursday after living away for nearly five years. Police reached the scene and were preparing to send the body to Jessore General Hospital morgue, while efforts continued to detain the accused.
