A Suffolk man was sentenced Thursday to more than 11 years in prison for distribution of heroin.

Garth Salkey, 65, was sentenced to 135 months in the U.S. District Court for the Eastern District of Virginia.

Salkey pleaded guilty on Nov. 17.

According to court documents, from the summer of 2012 through May 2015, Salkey conspired with his son, Christopher, to distribute heroin in Suffolk and Portsmouth, according to a press release from the U.S. Attorney’s Office.

Garth Salkey, who has been convicted of drug crimes on three prior occasions, received a significant quantity of heroin from his supplier on a regular basis, according to the press release. Garth Salkey would then add chemical cutting agents to the heroin, cap the drug into capsules, sell the capsules from two residences he owned and other locations, and collect drug proceeds. Garth Salkey recruited his son and others to help him in these activities.

According to court documents, four controlled purchases were made at Salkey’s Suffolk residence in April and May of 2015, according to the press release.

Based on the controlled purchases, the Suffolk Police Department and federal agents from the Drug Enforcement Administration executed a search warrant on May 20 at Salkey’s residence in Suffolk. Law enforcement recovered a quantity of heroin and packaging material used for distribution.

During the execution of the search warrant, Salkey threw about an ounce of heroin out of his bedroom window in an attempt to hide it from law enforcement, according to the press release. Additionally, agents also discovered a sophisticated marijuana grow operation with 129 marijuana plants belonging to Salkey’s son.

During the course of the conspiracy, it is estimated that Salkey and his son distributed at least eight kilograms of heroin, while Garth Salkey was personally responsible for more than four kilograms of heroin, according to the press release.

According to court documents, Salkey will be asked to forfeit $25,296 in cash recovered from the address on Meadow Country Road, a 2008 Chevrolet Suburban, a 2006 BMW M5, and $11,084.82 seized from a Bank of America account. A monetary judgment of more than $422,000 also is levied.
