Police have recovered the bodies of a woman and her three-month-old baby boy from Ashurail village under Nasirnagar upazila in Brahmanbaria.
The deceased are Farzana Akhter, 22, wife of Dubai expatriate Nur Uddin and their son Shafiqul Islam.
Police said Shafiqul's body was found on the bed while Farzana's was found hanging from a guava tree in the courtyard of their house on Friday morning.
Nasirnagar Sub-Inspector Shahjalal said: “The locals are assuming that Farzana might have killed her son and later committed suicide by hanging herself."
He said: “The truth behind the incident will be unveiled only after investigation. The bodies were sent to district sadar morgue around 9:30am.”
Family sources said Nur was supposed to return to Dubai on Saturday.
