Two men who had previously pleaded guilty to federal drug charges — charges that stemmed from their working to bring cocaine to Waldo County — were sentenced in U.S. District Court May 24.

U.S. Attorney Paula D. Silsby announced in a press release that Ralphy Dominguez, 25, of Bronx, N.Y., and Richard Calligan, 33, of Searsmont were sentenced as a result of their prior guilty pleas to charges of conspiracy to possess with intent to distribute and conspiracy to distribute cocaine.

Dominguez received five years in prison, three years’ supervised release and was charged a $100 special assessment and a $1,000 fine. Calligan received five years and seven months in prison, three years’ supervised release and was charged a $100 special assessment and a $10,000 fine.

According to the press release from Silsby’s office, court records revealed that between January 2005 and March 2009, Dominguez and Calligan, who were members of a cocaine distribution conspiracy that stretched from Waldo County to the Bronx, N.Y., conspired with others to possess with the intent to distribute and to distribute at least five kilograms of cocaine.

Evidence revealed that, on a weekly basis, Dominguez would supply Calligan and others with five to 15 ounces of cocaine that Calligan and others would redistribute to others in Waldo County. According to the press release, investigators determined that the conspiracy moved approximately 36 kilograms of cocaine during the course of the two men’s involvement in the conspiracy.

Dominguez was arrested in Waldo County on March 13, 2009, and was found to be in possession of 10 ounces of cocaine that he was to deliver to a customer in Waldo County, according to the press release.

Silsby praised the work done by the Maine Drug Enforcement Agency Mid-Coast Task Force, and also recognized assistance provided by the Waldo County Sheriff’s Office, the U.S. Drug Enforcement Administration and U.S. Immigration and Customs Enforcement. The investigation was conducted over the course of a year.
