A 23-year-old man who had married an upper caste girl from Hyderabad against her parents' wishes, and then gone missing nearly a month ago, was killed by his father-in-law in front of his wife, the police said on Saturday. Police claim that the wife, 20-year-old Tummala Swati, was forced to call her husband Amboji Naresh to a field on May 2 by her father Srinvas Reddy. There, Reddy killed Naresh with the help of his brother and nephew in front of Swati and then burnt the body to destroy evidence, police said.
