A final post-mortem report issued by JJ Hospital has confirmed that the deaths of four members of a family from Pydhonie in Mumbai were caused by zinc phosphide poisoning. However, the motive still remains unclear as the probe continued as on Friday.

The victims — Abdullah Dokadia (40), his wife Nasreen (35), and their daughters Ayesha (16) and Zainab (13) — died within hours after consuming watermelon at their home in Mogul Building on April 25.
