Dominican National Sentenced for Two Fentanyl Conspiracies

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

Guillermo Aybar-Guerrero, 29, was sentenced by U.S. District Court Judge Denise J. Casper to 52 months in prison.

Guillermo previously pleaded guilty to his role in two separate fentanyl conspiracies; for the purpose of sentencing, the two cases were consolidated. On June 9, 2021, Guillermo pleaded guilty to one count of conspiring to distribute and to possess with intent to distribute 40 grams or more of fentanyl and two counts of possession with intent to distribute fentanyl. On July 15, 2021, Guillermo 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.

Guillermo Aybar-Guerrero was indicted in August 2020 along with his brother, Luis 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.

Luis Aybar-Guerrero pleaded guilty on July 15, 2021 and is scheduled to be sentenced on Nov. 18, 2021 before U.S. District Court Judge Richard G. Stearns.

In the second conspiracy, investigators conducted controlled purchases of fentanyl pills from Guillermo on April 24 and May 5, 2019. The transactions were coordinated by co-conspirator Francis Jimenez Minyetty. Minyetty pleaded guilty to his involvement in the conspiracy and was sentenced in May 2021 to eight years 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 cases.
