A 42-year-old man, identified as Khunduraj Dhawalji, died by suicide by shooting himself with a revolver in Kalaburagi on Monday. Police suspect domestic discord as the cause, following a quarrel with his wife the previous night, after which she filed a complaint. Dhawalji, who had recently returned from working in Dubai, was alone at home when the incident occurred. An investigation is underway at the Chowk Police Station.
