GUILDERLAND — Stanislav Petkevichus, 28, of Guilderland, pleaded guilty on Oct. 27 to conspiring to distribute oxycodone, according to a release from the U.S. Attorney’s Office.

Petkevichus faces up to 20 years in prison and three years of post-imprisonment supervised release when he is sentenced on Feb. 22, 2017 by U.S. District Judge Mae A. D’Agostino, according to the release.

Assistant United States Attorney Michael Barnett told The Enterprise that Petkevichus admitted to conspiring to distribute oxycodone, which is an opiate. “Conspiring,” Barnett said, refers to agreeing with another person to distribute.

Petkevichus, who attended Guilderland High School and Clarkson University, admitted as part of his plea to obtaining about 200 oxycodone tablets from a co-conspirator between about November 2015 and January 2016, for resale in the Northern District of New York, the release says.

The case was investigated by the the federal Drug Enforcement Administration, the release says, and is being prosecuted by Assistant U.S. Attorney Jeffrey C. Coffman.

Petkevichus was arrested earlier, in June 2015, on Crossgates Mall Road for criminal possession of a controlled substance, a misdemeanor. According to the Guilderland Police report, officers received a report of a man passed out behind the wheel of a car in the mall parking lot. Petkevichus was discovered in his car, asleep, the report says, with burned aluminum foil and a lighter in his lap and a piece of marijuana on his shirt; after being awakened by officers, Petkevichus grabbed a black key box that contained 17 oxycodone hydrochloride 30-milligram pills. He also had $1,120 in cash in his wallet, the report said, and could not give a valid reason for having that amount of cash.
