A Connecticut man has been indicted by a federal grand jury and accused of dealing firearms and fentanyl in his home state and Rhode Island.

Daniel Alexander Smith, 19, of Windsor, was arrested last Tuesday and ordered detained during a hearing in federal court in Providence, according to the U.S. Attorney’s Office for the District of Rhode Island. The indictment, which was initially sealed, was announced by federal officials on Tuesday.

According to federal authorities, between February and May, Smith sold seven firearms and 90 grams of fentanyl during several transactions while under surveillance by members of the Rhode Island FBI Safe Streets Task Force.

In four of the sales, which occurred in Rhode Island, federal authorities allege Smith sold an AK-47, a Glock 26, a High Standard revolver, a Taurus 9mm handgun, two .22 caliber pistols and about 40 grams of fentanyl. According to federal officials, he also sold a Glock 19x pistol, a High Standard shotgun and about 51 grams of fentanyl in Connecticut while he was under surveillance.

“In each instance, the firearms and fentanyl allegedly sold by Smith were quickly seized by members of the Safe Streets Task Force,” Zachary A. Cunha, U.S. Attorney for the District of Rhode Island, said in a statement Tuesday.

Cunha also said authorities carried out a search warrant on Smith’s vehicle when he was arrested last week and seized a loaded automatic Glock 22 firearm with a sear switch attached and a 22-round magazine.

The indictment against Smith charges him with engaging in the business of dealing in firearms without a license and conspiracy to distribute 40 grams or more of fentanyl.
