A north Minneapolis man has pleaded guilty in connection with what federal authorities believe to be the largest single methamphetamine bust in Minnesota history.

Federal prosecutors say 34-year-old Fernando Ramos-Meza pleaded guilty Wednesday to conspiring to distribute about 191 pounds of meth. Ramos-Meza and three other suspects were indicted in November.

U.S. Attorney Erica MacDonald says officers with the Canon River Drug Task Force found the drugs along with a sawed-off pump shotgun during a search in September.

MacDonald says the quantities of meth coming into Minnesota continue to rise and the “destruction that comes with it cannot be understated.”
