Fort Thompson man pleads guilty to failing to register as sex offender

A Fort Thompson man pleaded guilty Wednesday to failing to register as sex offender.

Sheldon St. John, 47, appeared before U.S. District Judge Roberto Lange. The maximum penalty for the violation is 10 years in prison, a $250,000 fine or both.

St. John has been convicted in federal court for abusive sexual contact. He was on supervised release for three years and left Glory House in Sioux Falls in February 2010.

St. John was aware he needed to register quarterly and within five days of moving to a new location for his entire life. After he left Glory House, he did not register.

The Bureau of Indian Affairs arrested St. John in Fort Thompson in March 2010.

Lange ordered a presentence investigation and set sentencing for November.

St. John remains in the custody of the U.S. marshal.
