Agra, Feb. 22 -- Five members of a family - a 50-year-old man, his wife and three children - were found dead in a room locked from inside at Nagla Bhojraj village on Etah road in Kasganj district's Amanpur area on Saturday evening, police said. The children were aged nine, 10 and 12 years. While the man was found hanging, the woman had an injury mark, apparently inflicted by a sharp object. The three children were suspected to have been poisoned. Prabhakar Chaudhary, deputy inspector general (DIG) of police, Aligarh range, confirmed information about five bodies in the Kasganj house. It was too early to determine the exact reason for the deaths, he said. "Police found the room locked from inside and broke the door open to find five bodies inside. The man was found hanging while his wife had injury marks on the neck. Three minor children were found lying dead. They had no injury marks," the DIG said. "There was no sign of forced entry. It is suspected that the man might have poisoned the children and then hacked the wife to death before hanging himself. This is subject to investigation," he said. "All aspects related to family background (will be looked into) and statements will be recorded," Chaudhary said....
