Jeffrey Sloan, of Central Islip, charged with selling drugs that caused fatal overdose 

A Central Islip man was arrested and arraigned on 31 charges, including possessing fentanyl and other drugs with the intent to sell them, after an investigation into the fatal overdose of a 25-year-old man to whom he allegedly sold narcotics, Suffolk officials said.

Text messages and surveillance footage obtained from a convenience store allegedly indicate Jeffrey Sloan, 62, sold drugs to a Brentwood resident who died of an overdose, according to a news release from Suffolk County District Attorney Ray Tierney.

An investigation into Sloan began after Suffolk police responded to the scene of a fatal drug overdose at a Brentwood residence on Feb. 6, according to the release. Police recovered nine envelopes containing residue from a mixture of drugs, including cocaine, fentanyl, heroin and ketamine, plus a pill containing Xanax, and the dead man's cellphone.

Text messages on the phone indicated he arranged to meet Sloan at a 7-Eleven on Crooked Hill Road in Brentwood on Feb. 4, according to Tierney’s office. The two men negotiated a sale of 13 bags of heroin and a single Xanax pill for $140.

A review of surveillance footage from the convenience store showed a man withdrawing cash at an ATM before Sloan arrived and allegedly engaged in what appeared to be “a hand-to-hand narcotics transaction,” according to the release.

The Suffolk County medical examiner found cocaine, fentanyl, fentanyl-related synthetic opioids, heroin and ketamine during an autopsy and deemed “a mixed drug intoxication” to be the cause of death, Tierney’s office said.

In a search of Sloan’s home, camper and trio of vehicles on Feb. 19, Tierney said police found a mixture of fentanyl and heroin, along with Xanax and oxycodone pills, and a ledger detailing drug transactions.

Rashad Sloan, 33, was also present at the Central Islip home as police conducted the search, Tierney said. In his bedroom, police allegedly found “a pistol, a high-capacity magazine, a quantity of cocaine, a digital scale, drug packaging material and cash,” according to the release.

Officials did not reveal any relation between the two men, who were arrested that same day, according to court documents.

On Monday, Jeffrey Sloan pleaded not guilty in Suffolk County Court to numerous counts of criminal possession and sale of a controlled substance, Tierney's office said.

He is scheduled to return to court on March 27. His attorney, Adeline Arvelo, could not immediately be reached.

Also on Monday, Rashad Sloan pleaded not guilty to two counts of third-degree criminal possession of a controlled substance, third-degree criminal possession of a weapon, criminal possession of a firearm and two counts of second-degree criminally using drug paraphernalia, according to Tierney’s office. He is due in court on April 3. His attorney, Raymond Perini, could not immediately be reached.
