A Suffolk man was sentenced Tuesday to more than eight years in prison for possession of fentanyl with intent to distribute.

Glenn Murphy, 39, was indicted and arrested in September 2018 after an undercover investigation by the Portsmouth Police Department and the U.S. Drug Enforcement Agency, according to court documents.

He distributed about 83 grams of heroin during the investigation, according to a statement of facts filed in U.S. District Court for the Eastern District of Virginia. A confidential informant purchased the drugs from Murphy on three occasions, according to the document.

On March 29, 2018, the informant placed a phone call to purchase more heroin. When Murphy showed up at the prearranged location to make the sale, he was taken into custody.

When Murphy was searched after the arrest, law enforcement officers found a combined total of about 78 grams of fentanyl, 12 grams of a fentanyl derivative and 28 grams of cocaine.

Murphy was indicted on charges of distributing cocaine, two counts of distributing heroin, possession with intent to distribute fentanyl and possession with intent to distribute cocaine. He pleaded guilty only to possession with intent to distribute fentanyl as part of a plea agreement.
