A Suffolk man on Wednesday pleaded guilty to charges of conspiracy to distribute heroin and possession of a firearm as a convicted felon.

From summer 2012 to May 2015, Christopher Salkey, 31, conspired with his father and two co-conspirators to distribute heroin in Suffolk and Portsmouth, according to a press release from the U.S. Attorney’s Office.

Each week, Salkey and his father would receive a significant quantity of heroin, to which they would add a cutting agent and then cap it up for distribution, according to the press release.

During the course of the conspiracy, it is estimated they distributed at least eight kilograms of heroin.

On May 20, the Suffolk Police Department and federal agents from the Drug Enforcement Administration executed a search warrant at the residence in the 2000 block of Meadow Country Road. They recovered heroin, packaging material, a marijuana grow operation with 129 marijuana plants, two hidden firearms, $25,000 in cash, $26,000 in gold bullion and more.

Salkey was charged by criminal complaint on Sept. 18. He faces a minimum sentence of 10 years and a maximum sentence of life in prison when he is sentenced on Feb. 18.
