A Providence man who was found to be carrying a kilogram of fentanyl when stopped by police in Old Lyme in 2017 has been sentenced to 30 months in prison, followed by three years of supervised release.

U.S. Attorney John H. Durham announced the sentencing of Alcides Alba-Gomez, 29, in a news release on Thursday.

Alba-Gomez and his associate, Gabri Javier Delapaz, were traveling from Rhode Island to New York to pick up narcotics from a supplier on Sept. 13, 2017, according to court documents and statements.

On their return, police stopped them on Interstate 95 and found the fentanyl hidden beneath a seat cushion. At the time, police said that much fentanyl has an approximate street value of $1 million.

According to a police report from 2017, police had tracked the Honda Accord from Branford to Old Lyme after receiving information that two men would be transporting a large quantity of illegal drugs.

Alba-Gomez has been detained since his arrest that day, the news release said, and he pleaded guilty on Jan. 24 of this year to possession with intent to distribute 40 grams or more of fentanyl.

Delapaz, who was driving the car, pleaded guilty and awaits sentencing.
