U.S. Attorney Barbara McQuade said investigations of deaths linked to heroin are a priority in her office. She said heroin is “poison,” and the people who sell it are aware of the risk.

The government says more than 60 people have died of overdoses of heroin and fentanyl in Wayne and Washtenaw counties this year. Nationwide, heroin overdoses have tripled since 2010, according to the DEA.
