After 54 years of marriage, things turned sour between the retired insurance officer and his wife, 78. Accusing her of not caring for him any longer, in a fit of rage he beat her to death.An 82-year-old retired insurance officer killed his 78-year-old wife in a fit of rage - and then called the Thane police, asking them to arrest him so that he would be punished for his crime.Umakant Sule and his wife Pushpa had been married for 54 years. They lived in a first floor flat in the plush Cosmos Complex at Ghodbunder Road in Thane. Their only daughter is married, and lives with her in-laws in the Upvan locality of Thane.On Thursday morning, the police control room received a call from Sule, who informed them that he had killed his wife. He proceeded to give the police his address, and waited there for them to arrive.The control room informed the Kasarvadavli Police Station, from where a team was sent to investigate.According to the police, Sule was calm as he ushered them in. He took the cops to his bedroom, where his wife was lying in a pool of blood. Sule then gave the police a stick he had used to attack his wife, and asked them to arrest him so that he is punished for his act.After living together for more than five decades, things turned sour between the couple over the past few years. “During initial questioning, the accused said that for several months his wife’s behaviour towards him had been rather odd. He said she would keep taunting him for one thing or the other thing, and stopped paying any heed to his needs and requirements,” a senior officer from the Kasarvadavli Police Station said.“On Wednesday night, a heated argument took place between the two, and the accused again accused his wife of not taking care of him. He said she was very arrogant and said that she would not care for him anymore, and he could do whatever he wanted.“Later, while she was asleep, Sule allegedly attacked her with the stick, hitting her on the head and all over the body. He didn't sleep the whole night, and in the morning called the police to surrender,” the officer added.Sule's daughter, who is in a state of shock, told the police that few days ago he had come to her residence after a routine quarrel with her mother. He said that he didn't want to go home, and wanted to stay with her or else he would commit suicide.The daughter told the police she somehow managed to convince her father, and sent him back home. She said she never imagined that things would go so far that, at this age, her father would kill her mother.“The couple would have heated arguments, but we never thought that Sule uncle would kill his wife. The news came as a shock to us this morning,” said a neighbour of the Sule family.DCP Ashok Dudhe told Mirror, “Sule was produced in court and has been remanded in magisterial custody for 15 days.”
