According to police, Shane Eisener, 40-years-old, is charged with Class A, Aggravated Trafficking in Schedule W Drugs (Heroin/Fentanyl)

For the past two months, agents assigned to MDEA’s York District Task Force have been investigating the sale of heroin by Eisener and others who routinely travel to Massachusetts in order to purchase large amounts of heroin to be sold in greater Sanford, said police.

Late Friday night  drug agents with assistance from State and Wells Police stopped a car on the Sanford Road in Wells that Eisener was a passenger in. Police said the car was returning from Lawrence, Massachusetts with heroin and cocaine.

Seized from Eisener was 42 grams of a heroin/fentanyl mix and 15 grams of cocaine HCL. The approximate street value of the seized drugs is $7,800, said police. The operator of the vehicle was released pending review of potential charges by the State’s Attorney General’s Office at a later date.

Eisener was transported to the York County Jail  and being held without bail because he was already out on bail for an unrelated charge. He is expected to make a court appearance today.

The investigation is continuing and others associated with Eisener have been identified. Additional arrests are expected.
