LEWISTON — A local man pleaded guilty Thursday to trafficking the prescription painkiller oxycodone in Lewiston last summer.

Mark R. Hancock, 52, of 17 Jefferson St., pleaded guilty to a charge of drug trafficking as part of a plea agreement in which other charges were dropped.

Hancock was sentenced to four years in prison with all but one year suspended.

According to court documents, Hancock was accused of selling oxycodone in August by providing pills to a woman who would sell them and hand over the proceeds.

Hancock was originally charged with five counts, including aggravated trafficking and charges of conspiracy to traffic drugs. However, those counts were dropped when Hancock agreed to plead guilty to the charge of unlawful trafficking.

As part of the arrangement, Hancock was granted a stay of execution, allowing him to remain free until April 7.

His arrest in August was not the first time Hancock has been in trouble for drug trafficking. In 2012, he was arrested when Lewiston police and drug agents raided an apartment at 51 Pierce St. Drug officials said Hancock, who was wanted after escaping from a prison farm in Texas, was found with a large amount of pre-packaged marijuana, prescription drugs and several firearms.

In that case, he was arrested on charges of aggravated drug trafficking, possession of oxycodone and possession of a firearm by a felon. He was ultimately convicted of trafficking in marijuana.

Investigators said Hancock has been known to use several aliases, including the names David Laliberty, David Laliberi, Al Liberti and Al Beezie.
