Authorities are continuing efforts to crack down on the methamphetamine trade on the Yankton Sioux Reservation in southeastern South Dakota.
U.S. Attorney Brendan Johnson says a federal grand jury has indicted a group of seven people on drug charges including conspiracy to distribute meth. A group of five people was indicted last December.
The effort to crack down on meth use on the reservation picked up steam in 2012 when a 2-year-old girl died in a home where authorities said meth was prevalent.
Then-Wagner Police Chief Jim Chaney also resigned that year for covering up his girlfriend's meth use.
