Agra, Jan. 21 -- An Etah man was on Tuesday arrested for the gruesome murders of his parents, wife and daughter in their residence, police said. Investigators said financial distress ahead of his daughter's wedding could be the trigger. Ganga Singh, 75, his wife Shyama Devi, 68, daughter-in-law Ratna Devi, 40, and granddaughter Jyoti, 23, were aggressively struck on their head with a brick at their Kotwali Nagar residence on Monday, police said. Kamal Singh, Ganga and Shyama Devi's son, had an altercation with his wife, who reportedly reprimanded him for not arranging sufficient funds for their daughter's wedding, on Monday afternoon, after which he assaulted all family members present in the house, they suspected. DIG-Aligarh Range Prabhakar Chaudhary said Kamal, 44, had confessed to the murders and told police that he intended to kill himself, too, but returned home after one of his daughters called him to inform him about the deaths. "After the incident on Monday, police teams were constituted for the investigation. They found CCTV footage showing Kamal Singh reaching the house around 12.55pm on Monday and leaving on a motorcycle about 75 minutes later." "His 10-year-old son reached home about 20 minutes later. No individual is seen going in or moving out of the house in these 20 minutes. Kamal's elder daughter had called her younger sister before the incident, and confirmed Kamal's presence at home," the DIG added. "Call detail records, our investigation and forensic evidence all suggest Kamal's involvement as blood stains were found on his shoes and clothes. His finger tips and palms had bruises suggesting he handled a heavy object. Police recovered the brick, which was brought from the roof of the house and used to batter the family," added Chaudhary. "Kamal's mother heard the scuffle and came to intervene. She fell after she was pushed aside with the help of the brick. Then, Kamal went to his father, who was battling cancer, and struck him in the head, too," stated the DIG. htc...
