Anderson Police are digging deep to find out who poisoned three Anderson teenagers, killing one of them. The 13-year-old and two 16-year-olds apparently thought the substance was Cocaine when somebody provided it to them. It was actually Strychnine. The three were rushed to a hospital where one of the 16-year-olds died and the other teens are still suffering the effects of the poison. Investigators have gotten some leads.
