EVANSVILLE, Ind. — Vanderburgh County in southwest Indiana already has had 18 people die from heroin overdoses this year, triple the number from a year ago.

The victims have ranged in age from 24 to 58 and only four of the deaths in 2016 have been women. Chief deputy coroner Steve Lockyear tells the Evansville Courier & Press (http://bit.ly/2ck5Vxu) many of the people who have died this year from heroin overdoses have also had fentanyl in their system.

Fentanyl is another powerful opioid that authorities have long warned is often added to heroin to make it more potent. That added potency gives the drug an even higher overdose potential.
