KILL DEVIL HILLS, N.C. (WVEC) -- A Kill Devil Hills man is facing charges after the Dare County Narcotics Task Force found what is believed to be “Gray Death.”

Authorities conducted a search warrant at a residence in the 100 block of West Durham Street. They seized approximately two ounces of "Gray Death."

Authorities say the deadly drug concoction contains carfentinal, fentanyl and heroin.

“You’re looking at somewhere upwards of about five thousand times stronger than heroin would be,” said Dare County Sheriff Captain Kevin Duprey.

Fentanyl is used in pain management and is 50 times stronger than Heroin. Carfentinal is used in elephant tranquilizer and is 100 times stronger than Fentanyl.

“Two milligrams can bring down a two thousand pound elephant,” said Duprey. “What it would take for a human body to have that same reaction to it would definitely be less than two milligrams.”

Duprey says local dealers are getting the drug from Virginia and bringing it back to Dare County. He said anyone who accidently inhales or touches the drug is at risk of death.

“The small amount that it takes to tranquilize an elephant will possibly kill you,” said Duprey.

Carfentinal and fentanyl are mixed into heroin because it’s cheaper. Duprey says drug users are turning to it for a greater high or are unknowingly consuming it.

“We just hope that users understand the possibility of dying is there and there might not be anyone around to save you,” said Duprey.

Mark Allen Thompson, 56, is facing felony charges of trafficking opium or heroin, selling/delivering Heroin and maintaining a dwelling for a controlled substance. Thompson is being held in lieu of a $750,000 secured bond.
