Authorities allege that Gerald J. Sadkowski, 30, of Watertown, and Brian M. Faulkner, 37, of Lynn, sold the pain killer illegally both on postal property and while out on their routes as postal employees.

The federal complaint says this took place between July and October.

If convicted on these charges, they face up to 20 years in prison, followed by three years of supervised release, and a $1 million fine.

According to documents recently released by the U.S. Drug Enforcement Administration, for at least nine years Khan has been internationally trafficking opium, heroin and morphine from headquarters based in Kandahar and Helmand, Afghanistan.  The trafficking ring is known as the “Khan Organization.”

The report states the Khan Organization planned on selling morphine base, which can be used to create heroin, in amounts as large as 40 tons to worldwide drug markets. Forty tons of morphine base would be able to satisfy the heroin needs of the U.S. for more than two years.

The organization also supposedly operated its own labs, producing refined heroin and selling it in quantities of 220 pounds or more.

According to DEA reports, Khan has been closely linked with the Taliban. The group draws much of its funding from drug organizations like Khan’s. In return for this funding, the Taliban provides protection over drug routes, labs and poppy fields.

Khan has supported the Taliban’s efforts to forcibly remove the U.S. and its allies from Afghanistan by backing their policy and funding their organization.  The terrorist group has repeatedly attacked U.S. forces and civilians in Afghanistan.

In January, the Taliban claimed responsibility for the bombing of a hotel in which an American was killed.

“His arrest disrupts a significant line of credit to the Taliban and will shake the foundation of his drug network that has moved massive quantities of heroin to worldwide drug markets,” said Michele M. Leonhart, acting DEA administrator.

If convicted, the 54-year-old faces a minimum of 20 years in prison and a maximum sentence of life.  A conference will be held Tuesday before a judge.

Khan is one of the first to be prosecuted under the federal narco-terrorism statute drafted in 2006.

WIlliam Patrick Jordan, 37, faces five years in prison and a $250,000 fine after an investigation revealed he was allegedly selling 50 to 70 hydrocodone pills twice a week for over a year at the restaurant, according to a statement from the Drug Enforcement Administration.

According to the charge, a confidential, undercover federal informant sold Jordan 40 hydrocodone tablets for $120, purportedly for resale. DEA agents swooped in and arrested Jordan, who was released on bond pending a hearing October 29. He faces charges of knowingly, unlawfully, and intentionally possessing hydrocodone with the intent to distribute.
