A 37-year-old man died on Thursday after his third wife allegedly splashed hot water on him for marrying a fourth wife.
Levis Odwori, a fisherman based at Mageta island, died after sustaining serious injuries during the incident.
His grandmother Resula said Odwori called her while undergoing emergency treatment at a hospital.
She said she sent one of Odwori's younger brothers to the hospital but by the time he got there, Odwori had already passed on.
Police have launched a manhunt for Odwori's wife who is said to have gone into hiding.
The deceased's body was taken to Bondo subcounty hospital mortuary.
The incident occurred a few weeks after a woman from the same area killed her pastor husband on suspicion that he was planning to marry another wife.
