A Portland man at the heart of a marijuana smuggling ring was sentenced Wednesday to nine years and two months in a federal prison.

David Jones, 30, was charged after an associate who was driving 100 pounds of marijuana from California to Maine in 2012 was stopped and arrested in Kansas. In October 2013, agents with the federal Drug Enforcement Administration and the FBI executed search warrants and seized $292,000 from Jones’ rented storage trailer, $92,000 from an associate’s apartment and $6,000 from his home, according to a news release from the U.S. District Attorney’s Office.

Agents also seized two boats, a truck, several motorcycles, two trailers, jewelry and electronics as part of the investigation.

The money and items, allegedly purchased with drug proceeds, were forfeited to the government.

Authorities say Jones smuggled 5,500 pounds of marijuana into the state between August 2011 and October 2013 via the U.S. Postal Service.

Agents also learned that Jones laundered about $177,500 in drug money through former Saco attorney Gary Prolman and another $39,000 through an associate, Michael Paul Jr., an Old Orchard Beach businessman, the release said.

Prolman was sentenced in December to two years in prison for money laundering. Paul has yet to be sentenced.

Jones, who goes by the nickname “David Kaos,” pleaded guilty Dec. 10 to two counts of conspiracy to distribute marijuana and two counts of conspiracy to launder money, and aiding and abetting. U.S. District Court Judge George Z. Singal sentenced Jones on Wednesday in federal court in Portland.

Portland police and the Organized Crime Drug Enforcement Task Force also were part of the investigation.
