Authorities in Chicago are investigating heroin that is being blamed for a series of overdoses Saturday. Chicago police say investigators are talking to a person of interest in connection with the overdoses.
Fire department spokesman Kevin MacGregor says 15 people received emergency medical care after using heroin purchased in the city's West Humboldt Park neighborhood. No deaths were reported. He says three of the people who became ill were discovered in a garage that was being used as a shooting gallery.
A hazardous materials team was dispatched to clean up the garage because between 100 and 200 used hypothermic needles were found discarded there.
Dozens of people have overdosed in Chicago this year including ten who've died after using heroin mixed with the synthetic painkiller fentanyl.
