Azamgarh: A couple and their teen daughter were hacked to death, allegedly by their 20-year-old son, in the Kaptanganj area of this Uttar Pradesh district, police said on Sunday.
The accused is absconding, Superintendent of Police Anurag Arya said.
The police said Rajan Singh, a resident of Dhandhari village in Kaptanganj, allegedly committed the triple murder after being reprimanded by his father a couple of days ago.
