BANGOR — A New York City drug dealer was sentenced Monday to 100 months – or more than eight years – in federal prison for conspiracy to possess with intent to distribute and with distribution of oxycodone and cocaine.

U.S. Attorney for Maine Thomas E. Delahanty II said Kenneth Robinson, 46, who went by the nickname of “Kill,” was also sentenced to three years of supervised release.

Robinson pleaded guilty in March 2013 to the charges.

The conviction stems from Robinson’s involvement in a large drug trafficking operation in central Maine. Court records indicate that he supplied oxycodone for distribution by a network of conspirators.

The network was dismantled following a three-month investigation by the U.S. Drug Enforcement Administration and Maine Drug Enforcement Agency.
