Joseph Patrick Coates of Pearl, Daniel Blake Huber of Jonesboro, Ark., and Charles Autry of Palestine, Ark., were sentenced this week in U.S. District Court in Jackson.
Coates' father, David Coates, and his sister, Mary Alice Coates, were arrested in the same undercover investigation. David Coates was a longtime coach at Northwest Rankin High School.
Patrick Coates was sentenced to 9 years, Huber to nearly 3 1/2 years and Autry to 3 years.
Federal drug agents said the investigation targeted club drugs, including ecstasy, LSD and high-grade marijuana. The alleged ring operated in Hinds, Madison, Rankin, Lafayette and Forrest counties.
