LAHORE, April 11: Police have not so far been able to solve the mystery surrounding the death of Dr Shahid Masood, his wife Dr Samina and their two-month-old daughter Amna, who were found dead in their bedroom at Dr Shahid’s official residence in Mayo Hospital late on Thursday night.

“The preliminary autopsy report has suggested that they have all been poisoned,” Investigating Officer SP Farhan Baig told reporters, expressing his belief that the doctor had committed suicide after injecting poison into the bodies of his wife and daughter. Empty injection bottles and syringes, found near the bodies, indicated that the doctor had used an overdose of anaesthetic, he said.

The motive has not yet been ascertained.

The bodies were returned to their families after autopsy. The doctor’s was taken to Layyah and his wife’s and the suckling’s to Toba Tek Singh.

The SP quoted doctors as saying that injection marks were found on the wrist of the doctor and in the head of his daughter while his wife already had a branula on her wrist. “She had been getting a pain-killer injection for some weeks.”

That’s why there was no sign of resistance as her husband administered the poison which she must have taken as the pain-killer, another investigator said.

Dr Shahid’s father, Abdul Majeed, claimed that the couple were leading a happy life and there was nothing that could have forced his son to kill his wife and daughter and commit suicide.

Dr Samina’s father, Mohammad Hafeez, termed his daughter’s death a murder, saying that he would pursue the case to its logical conclusion.
