SISSETON, S.D. - Three men have been charged with or convicted of sex crimes against children in northeastern South Dakota in cases that date back at least a decade.
The cases were investigated by the FBI or the Sisseton-Wahpeton Sioux tribe. It wasn't immediately clear if they're connected.
The U.S. attorney's office says 39-year-old Desi Campbell, of Summit, was sentenced to seven years in federal prison for sex crimes against a child under 12 between 2004 and 2008.
Fifty-six-year-old David Seaboy Sr., of Peever, has pleaded not guilty to a similar charge arising from November 2007. He's to stand trial Oct. 16.
In another similar case from 2007, 63-year-old Roland Brant has pleaded not guilty and is set for trial Oct. 16. He's currently in a treatment program in Minnesota.
