A Massachusetts man has been convicted in Maine of a heroin trafficking conspiracy charge, according to the U.S. Attorney’s Office.

U.S. Attorney Halsey B. Frank said in a statement Friday that Myron “Templer” Crosby Jr., 54, of Springfield was convicted Thursday following a four-day jury trial in U.S. District Court in Bangor. Crosby was found guilty of conspiracy to distribute and possess with the intent to distribute a kilogram or more of heroin.

Evidence presented at the trial showed that between August 2015 and January 2016, Crosby supplied between 60,000 and 80,000 bags of heroin, totaling more than a kilogram, from his operations in Hartford, Connecticut, and Springfield, Massachusetts, to co-conspirators from the Newport area who distributed the drugs in and around Newport, Frank said.

Crosby faces a sentence of 10 years to life in prison, an $8 million fine and eight years to life of supervised release, it said.

The case was investigated by the U.S. Drug Enforcement Administration with assistance from the Maine and Massachusetts state police. It was prosecuted as part of the U.S. Department of Justice’s strategy to combat the opioid epidemic, the U.S. Attorney’s Office said.
