Boston police raided two residences in Dorchester over the past week, seizing nearly 100 grams of fentanyl and nearly $90,000 in cash from two men charged with trafficking the drug, the Suffolk County District Attorney’s Office said Wednesday.

In a Nov. 23 raid, members of the Boston Police Drug Control Unit executed search warrants on the home of Cleifit Cruz, 33, of Dorchester, where they seized more than 27 grams of fentanyl, crack cocaine, and $80,456 in cash, the Suffolk County District Attorney’s Office said.

Cruz was charged Monday with trafficking fentanyl over 10 grams and possession to distribute a class B substance. He was held on $10,000 bail and his bail in another case in Norfolk County was revoked, according to prosecutors.

Cruz is due back in court in Dorchester on Jan. 24, 2025. He is also facing fentanyl trafficking charges out of Norfolk Superior Court and Quincy District Court, according to the Suffolk County District Attorney’s Office.

In a Nov. 26 raid, Boston police raided the home of Wilbil Aguasviva-Peguero in Dorchester, where they seized 72 grams of fentanyl, two grams of crack cocaine, $5,761 in cash, and seven rounds of pistol ammo, prosecutors said.

Aguasviva-Peguero was charged in a Roxbury Court Wednesday with possession to distribute a class B substance, trafficking fentanyl 36 grams or more, and unlawful possession of ammunition, prosecutors said.

He was held on a $10,000 bail with GPS monitoring and home confinement if released, prosecutors said. He is due back in court Dec. 30.

Suffolk County District Attorney Kevin Hayden said a 23% decline in overdose deaths in Massachusetts through June compared to the previous 12 months is an incentive for all law enforcement and health agencies “to work even harder at reducing overdoses from deadly substances like fentanyl.”

“When we see a decline like this it tells us that the efforts by everyone involved are pushing results in the right direction, and we have to keep up that hard and important work. Taking fentanyl off the streets — and holding the people who degrade our neighborhoods by selling this deadly drug accountable for their conduct — is a continued step in that positive direction,” Hayden said in a statement.
