PORTLAND — A California man who supplied a Scarborough drug dealer with more than 770 pounds of marijuana was sentenced Nov. 17 in U.S. District Court to two years in federal prison.

Michael Bretzing, 55, of Grass Valley, California, pleaded guilty in June to one count of conspiracy to distribute marijuana.

By pleading guilty, Bretzing admitted that he supplied David Jones, also known as Dave Kaos, 30, in 2012 and 2013 with marijuana Bretzing grew in his home, according to court documents. The pot was mailed to Maine or driven cross country by Jones’ co-conspirators.

In addition to prison time, Bretzing was sentenced to four years of supervised release. He had been held without bail since June. Prior to that, he was free on bail.

Bretzing faced up to 40 years in prison and a fine of up to $5 million.

Bretzing’s role in the conspiracy came to the attention of law enforcement after Jones was arrested Sept. 5, 2012, in Ellsworth, Kansas, while overseeing the transport of marijuana to Maine in a car someone else was driving, according to court documents.

Jones pleaded guilty in December to two counts each of conspiracy to distribute marijuana and money laundering. He is scheduled to be sentenced in February.

Jones faces on the conspiracy charge a mandatory minimum sentence of 10 years in prison due to a prior drug conviction in state court and a maximum sentence of life. He also could be fined up to $8 million. On the money laundering charge, Jones faces up to 20 years in prison and a fine of up to $500,000.

In his plea agreement, Jones waived his right to appeal his sentence to the 1st U.S. Court of Appeals in Boston if he is sentenced to 12 1/2 years or less. He also agreed to forfeit more than $300,000 in cash and personal property worth thousands of dollars.
