Two people were arrested in Clarksburg on Friday following an undercover drug operation, involving what deputies believe is Fentanyl-laced heroin.

The Harrison County Sheriff’s Department Street Crime and Drug Unit (SCAD) arrested Tiffany M. Keller, 28, of Clarksburg and Price “Project” Patterson, 29, of Pittsburgh, PA.

Deputies said on Friday, they seized seven and a half bricks (380 stamps) of suspected Fentanyl-laced heroin in an undercover operation in the Adamston area of Clarksburg. Deputies said the seized drugs have a street value of about $4,000.

“The heroin SCAD seized was marked “Hook Me Up” and has recently been identified as containing Fentanyl, but it will need to be sent to the Crime Lab for confirmation.  As a result of the undercover operation, SCAD anticipates additional arrests in this case,” said Chief Deputy Jeff McAtee.

Deputies later executed a search warrant on a residence on South Linden Avenue in Clarksburg, where Keller and Patterson were arrested.

After executing the search warrant, deputies said they also found $2,488 in cash, used heroin stamps and needles, about 320 grams of K2 (synthetic marijuana) and drug paraphernalia, deputies said.

Deputies notified the Department of Health and Human Resources on scene, which responded and took custody of three small children who were in the residence at the time of the arrests.

Keller is charged with possession of synthetic marijuana with intent to distribute and conspiracy to distribute synthetic marijuana, both felonies.

Patterson is charged with delivery of heroin, possession of synthetic marijuana with intent to distribute and conspiracy to distribute synthetic marijuana, all felonies.
