Mumbai family of four death ruled zinc phosphide poisoning not watermelon

Forensics found traces of potent rat poison in victims

Mumbai police say a family of four died due to zinc phosphide poisoning, a highly toxic rat poison, overturning early suspicions that the deaths were caused by eating watermelon. Forensic tests detected traces of the chemical in the victims’ viscera. Investigators are now trying to determine whether the poisoning was accidental or deliberate.
