A Kishoreganj court on Monday sentenced two people to death for killing a man in 2014.
The convicts are Kazi Nazrul Islam, 41, and Sumona Begum, 35, both hailing from Brahmanbaria.
Kishoreganj Additional District and Sessions Judge Mohammad Abdur Rahim also fined them Tk 2 lakh each.
According to the case statement, Nabi Hossasin of Brahmanbaria married his second wife Sumona in 2012 and arranged her living at a rented house in Kishoreganj's Bhairab upazila.
While staying in Bhairab, Shila developed an affair with Nazrul.
When Nabi learnt about their relationship, Sumona called Nabi at her house on December 21 in 2014 and killed him with the help of Nazrul.
They later cut Nabi's body into six pieces and dumped it in different areas of Bhairab.
