i don't know if this story is true or not.
i do know that some of the stories are true on CSI.
i just watched CSI Miami in which they had ice mixed with candy.
ice as everyone knows or should know is heroin mixed with cough medicine.
so if you don't know about this and it is true. i suggest that you reinforce the don't take candy from strangers to your kids.
if you do know about this or this story isn't true, sorry i bothered you with it.
