A Rochester man who's already serving time in a double homicide was sentenced to 20 years in prison on federal drug trafficking and weapon charges.
Deadrick Fulwiley entered guilty pleas in May.
He and three other men were indicted last year for their roles in a marijuana trafficking ring.
Prosecutors say they battled another ring in a turf war two years ago that eventually led to the killings of Rochester Police officer Tony Mazurkiewicz and two other men.
Fulwiley was given 30 years to life in prison in May for the murders of Richard Collinge and MyJel Rand.
The federal sentence will run concurrently.
