For Immediate Release
U.S. Attorney's Office, District of Massachusetts

BOSTON – A Dominican national previously residing in Lawrence was sentenced today in connection with two fentanyl distribution conspiracies.

Luis Aybar-Guerrero, 25, was sentenced by U.S. District Court Judge Richard G. Stearns to 42 months in prison and two years of supervised release. He will be subject to deportation proceedings upon completion of his sentence. On July 15, 2021, the defendant pleaded guilty to one count of conspiring to distribute and to possess with intent to distribute 40 grams or more of fentanyl and one count of possession with intent to distribute 40 grams or more of fentanyl.

Luis Aybar-Guerrero was indicted in August 2020 along with his brother, Guillermo Aybar-Guerrero, after investigators conducted controlled purchases of fentanyl from Guillermo on June 10 and 17, 2020. On June 25, 2020, investigators set up another controlled purchase, at which time Guillermo was arrested in possession of approximately 30 grams of suspected fentanyl. Guillermo retrieved the fentanyl for each of these transactions from Luis. A search of Luis’ residence resulted in the seizure of an additional 223 grams of acetyl fentanyl (a fentanyl analogue) as well as a scale, baggies and other drug distribution paraphernalia.

On Oct. 27, 2021, Guillermo Aybar-Guerrero was sentenced by U.S. District Court Judge Denise J. Casper to 52 months in prison.

Acting United States Attorney Nathaniel R. Mendell and Brian D. Boyle, Special Agent in Charge of the Drug Enforcement Administration, New England Field Division made the announcement today. Assistant U.S. Attorney Lauren Graber of Mendell’s Narcotics and Money Laundering Unit prosecuted the case.
