A 65-year-old woman and her daughter were found dead with stab injuries at their residence in east Delhi’s New Ashok Nagar on Monday morning, police said.
Her son-in-law, Pankaj, and his two accomplices Ujjawal Dabas and Ajit allegedly shot bullets at the woman while she was in an e-rickshaw.
The bodies were in a putrefied state and it seemed that the murder had been committed around one week ago, Deputy Commissioner of Police (Northeast) Ved Prakash Surya said.
During interrogation, the accused told police that the boy had beaten up one of them some time ago and they decided to kill him to settle the score.
