A Turtle Creek man charged in connection with a heroin and cocaine conspiracy allegedly with his two sisters admitted to the crime in federal court Thursday.

Jerry Coker, 28, pleaded guilty to a count of conspiracy to distribute and possession with intent to distribute fentanyl and heroin.

Authorities said his sister, Marleka Robinson, obtained a large amount of fentanyl from a dealer in Knoxville at his request in September 2016.

She then came back to the house she shared with him and another sister, Monique Robinson.

Investigators searched the home the next day and seized more than 285 grams of fentanyl and smaller amounts of heroin, cocaine and marijuana.

Authorities said drug packaging and distributing materials were found strewn through the house, along with two guns and nearly $9,000 in cash.

A grand jury indicted Coker and his sisters in November 2017.

The sisters’ cases are pending.

U.S. District Judge Cathy Bissoon scheduled Coker’s sentencing for May 18.

He faces at least a decade in prison and could be sentenced to life due to a prior felony conviction.
