What started as a 2010 traffic stop that led to police finding $6,200 cash that smelled like marijuana inside a backpack in a Cranston man's car ended this morning with his sentencing to 76 months in federal prison.

United States Attorney Peter F. Neronha and Cranston Police Chief Col. Marco Palombo, Jr., today jointly announced that Jeffrey Batres, 29, pleaded guilty to federal drug trafficking charges and was sentenced by U.S. District Court Judge William E. Smith. Upon his release from prison, Batres will serve three years of supervised release.

Court records show Batres was arrested in August, 2010. Police seized the cash from the traffic stop and obtained a search warrant for Batres' house shortly afterwards.

At Batres' house, police found "significant quantities of cocaine and marijuana," according to a release.

A federal grand jury returned a two-count indictment in Oct. 2010 charging him with one count each of possession with the intent to distribute cocaine and more than 50 kilograms of marijuana. He pleaded guilty on June 6, 2011.

Police seized a total of 151 grams of cocaine and 78 kilograms, or 171 pounds, of marijuana and various items used for drug packaging and distribution.

The case was prosecuted by Assistant U.S. Attorney Sandra R. Hebert.

The matter was investigated by the Cranston Police Department.

Batres was previously convicted in state court and spent time in jail for drug trafficking and firearms charges, police said.
