Police in Northern California are trying to find out who gave a plastic bag of methamphetamine to a young girl on Halloween. Hercules police Sgt. Ezra Tafesse said the eight-year-old girl’s parents found powder packaged in a small zip-style bag among her Halloween candy and alerted police on Monday. Tafesse added that the girl had been trick-or-treating in the Promenade area of Hercules, a San Francisco Bay Area city, when she was given the bag containing one-tenth of a gram of crystal methamphetamine. It’s unclear if the girl was given the drugs intentionally or accidentally, and police don’t have a suspect.
