KARACHI, May 31: A couple and their one-and-a-half-year-old daughter were found bludgeoned to death in their rented house in Madina Colony within the remit of the Shah Latif police station on Thursday, police said.

The landlord told the police that he had come to the house and knocked at the door, but the family did not respond despite his repeated knocks.

He then informed the police who entered the house and found the bodies of Sohail Fazal, his wife, Shehnaz, and their daughter Sawera.

The police suspected that the victims might have been given some food laced with drugs to make them unconscious before they were bludgeoned to death with a block of concrete.

The police also found a marriage certificate in the house which showed that the couple had contracted a freewill marriage and they hailed from Bahawalpur.

The bodies were taken to the Edhi morgue after autopsies at the Jinnah Postgraduate Medical Centre as no one came to collect them.

Station House Officer of the Shah Latif police station Sajjad Hyder said that the slain family had rented the house about a month ago.

The police said they believed that the couple had got married without the consent of their families and that could be the reason of the triple murder.

An FIR of the incident was not registered till late in the night.
