KENSINGTON (WPVI) -- Police say a deadly batch of heroin on Philadelphia's streets is now being linked to at least nine deaths over the weekend.
Those people died within blocks of on another in what police are saying is one of the deadliest weekends in Kensington.
The victims ranged in age from their 20s to their 40s.
Police released the following details about those who died:
District Attorney Seth Williams said there could have been even more deaths if emergency personal didn't have NARCAN, which helps reverse the effects of an overdose.
"It's getting out of control here. We have our kids in the streets playing with needles and dope bags," said Lewis Lawson-Hill.
Williams is vowing to tackle the problem head on, one drug dealer at a time.
"We are going to do all that we can, with the use of undercover officers, people giving us information, to prosecute people spreading this poison in our community," Williams said.
Police are now sorting through baggies and evidence left at the scene to see if they can connect the deaths.
"To see whether or not there is something that is laced or cut, or if it's just the purity of it," said Lt. John Stanford.
Williams says this past spring his office purchased $50,000 worth of NARCAN that was distributed to police.
He credits it with saving lives.
"And to date, Commissioner Ross has trained 996 officers to inject people that have OD'd," said Williams.
Philadelphia Police say NARCAN has been used to save more than 150 lives so far this year, and that doesn't include lives saved by EMS and other emergency personnel.
In fact, four lives were saved just this past weekend.
