Police in Manchester are dealing with a recent spate of fatalities caused by drug overdoses.
Between Nov. 26 and Dec. 7, the city saw six overdose deaths.
Sgt. Brian O’Keefe says the department is waiting for toxicology results to confirm, but the suspicion is heroin use was involved in each case.
“Heroin today is roughly 30 to 40 percent purity," he said. "So if they add a few percentage of more pure ingredients such as heroin to the current product on the market, that can cause the uptick in fatalities.”
