Rochester, MN (KROC AM News) - A Rochester woman has pleaded guilty to a 1st degree drug charge stemming from a statewide crackdown on heroin trafficking last year.

The plea agreement worked out with 33-year-old Shaunda Gadsden resulted in the dismissal of two other felony drug charges. She is scheduled to be sentenced in February.

Rochester police made 2 arrests during the crackdown. The other defendant, 30-year-old Martinez Williams of Minneapolis, was sentenced to 90 days in the Olmsted County jail after he pleaded guilty in January. At the time of their arrests, both Gadsden and Williams were described as significant heroin dealers.

Throughout Minnesota, federal, state and local law-enforcement agencies rounded up over five dozen people in what officials say was the biggest heroin-related trafficking enforcement operation in state history.
