YONKERS - The Putnam County sheriff says he is waging war to get heroin dealers off the streets and behind bars.

There have been four heroin-related deaths in Putnam this year, and 13 last year.

While the county has been successful in cracking down on prescription drugs and other narcotics, Sheriff Donald Smith tells News 12 that the big problem is that heroin is cheap and easily accessible.

Narcotics enforcement officials in the area are trying to put the dealers behind bars in the hope of reducing demand for the drug.

However, Smith says it's an ongoing war against an enemy that rarely surrenders.

Smith does say that deputies are being currently trained on how to administer Narcan, a nasal spray that acts like an antidote when a person overdoses.
