Narcotics detectives and the Long Island Heroin Task Force were investigating the overdose, police said, and it led to Coles’ arrest at 4:45 p.m. Friday in Mineola. Police did not release details of the overdose, including when the person died.

The Long Island Heroin Task Force is a multiagency partnership that started last summer to battle the opioid epidemic and spike in drug deaths.
