The mystery surrounding the deaths of four members of the Dokadia family in Pydhonie deepened on Friday after police recovered a bottle of herbal rat repellent from their residence, a day after forensic reports confirmed the presence of lethal zinc phosphide in the watermelon consumed by the family.

The Forensic Science Laboratory (FSL) report, received on Thursday, May 7, confirmed that the family died after consuming watermelon laced with zinc phosphide, a highly toxic rat poison.
