An elderly woman was killed by her son allegedly over family feud in Mathbaria upazila of the district on Monday.
The deceased, Sajeda Begum, 59, wife of Abdul Jabbar, was a resident of Bholmara village in the upazila.
Baro Machhua Union Parishad Chairman Mohammad Nasir Ahmed said Sajeda's son Abdur Rahim, 30, got locked in a quarrel with her over different family issues.
At one stage, Rahim hacked his mother with a spade, leaving her dead on the spot.
Rahim later dumped the body in a pond adjacent to their house and went into hiding, the UP chairman said.
Later in the evening, Rahim phoned his brother-in-law Faruk Hawlader of neighbouring Ulubaria village and told him when and how he committed the gruesome murder.
Police sent the body to Sadar Hospital morgue for autopsy, said Mathbaria Police Station Officer-in-Charge (OC) KM Tarikul Islam.
The deceased’s husband Abdul Jabbar filed a murder case with the police station against Rahim yesterday, the OC said.
