Delray Beach police continue to express alarm about heroin overdoses in the city.
The department says officers answered 13 overdose calls from Friday to Monday and two resulted in deaths.
One of the victims was a 35-year-old man and other was a 26-year-old man.
In May officers responded to 17 heroin-related overdoses in which three people died.
Drug experts think people are turning to heroin because Florida cracked down on pain pill abuse.
Police suspect fentanyl, which is used to cut the heroin, is playing a role in the deaths. They say fentanyl is up to 50 times stronger than heroin and since there is no way to know how much is in any one dose, users are gambling with their lives.
Police urge anyone who suspects illegal drug activity or drug sales to call the DBPD Tip Line: (561) 243-7839.
DBPD officers have responded to 13 heroin overdoses in the past four days. Two were fatal. Call tip line with info: (561) 243-7839.
