no the guy did not add any poison and he is totally innocnet the ice in the punch was poisoned and it had not melted yet the man drunk some then pur some poisonous shi+ in the rest be4 the rest of the guests arrived He poisoned the punch AFTER he drank it, and then left. Either the man poisoned the punch or it became rancid from sitting out all day. he poisoned the juice? When the wedding started, the bride decided not to get married, the groom got pissed off and shot everyone. That is how they all died after they drank juice. Poisoned?
