AGRA, Feb. 11 -- A family of five - a farmer, his wife, and their three young children - were found dead in their home in Mathura's Khapparpur village on Tuesday, in what police suspect is a case of murder-suicide, officers said on Tuesday. Police recovered a diary with a suicide note from the farmer at the scene, alongside a video on his phone in which he claimed the family took their lives due to their own troubles. A message was also scrawled on a wall, officers said. ADG (Agra zone) Anupam Kulshrestha reached the village and prima facie held the case as that of collective suicide. A glass with traces of milk was found near the bodies, which made one believe that poison was used but the police were waiting for the post-mortem report to ascertain the cause of deaths. The deceased included a 35-year-old farmer, his wife aged around 32 and their two daughters -- aged 8 and 5 -- and a three-year-old son. They were found dead inside a room of their house, he said. "Prima facie, it appears a case of collective suicide at this stage on basis of what is written on wall of house, hand written statement of Manish in his diary and video traced from mobile of Manish which all are with police now' stated ADG Agra Zone. In the alleged suicide note written by the farmer, the 35-year-old stated that he and his wife were ending their lives because of their own sorrow and nobody is responsible for their deaths, according to the police. However, there was confusion as to how all these five ended their lives. A senior police official said that evidence available on the spot pointed towards strangulation of three children to death by their father who struck his wife on the head and then allegedly killed himself by electrocution. It was also revealed that the farmer was inclined towards ritualistic practices. The police also interrogated the farmer's brother, living near the house where the incident took place. But he was of view that it might be a case of suicide. "My brother (farmer) had sold a plot for Rs 15 lakh and received part payment for it, but the remainder was yet to be paid by the buyers," he told media. When the children didn't come out in the morning to play, the farmer's brother went inside the house after jumping the wall and broke open the door, and found his family members dead. He was accompanied by some villagers, said SSP (Mathura) Shlok Kumar. District magistrate Chandra Prakash Singh said the chief minister had also expressed grief over the incident and directed officials to provide full support to the family and probe the matter from all angles....
