PIERRE, S.D. (AP) - A Rapid City man accused of conspiring to distribute more than 100 kilograms of marijuana has pleaded guilty in federal court.

Brendan Johnson, U.S. Attorney for South Dakota, says 48-year-old Lyle Ferguson will be sentenced later for his conviction of conspiracy to distribute a controlled substance. The maximum sentence for the offense is 40 years in prison and a $5 million fine.

Johnson says the charge relates to Ferguson and others conspiring to distribute a large quantity of marijuana in South Dakota and elsewhere.
