United States Attorney Brendan V. Johnson announced that Mary Jo Flammond, a/k/a Mary Jo Waln, age 32, of St. Francis, South Dakota appeared before U.S. District Judge Roberto A.

The maximum penalty upon conviction is 8 years in custody, a $250,000 fine, or both; 3 years of supervised release; and a $100 special assessment.

Flammond was driving recklessly and could not keep the vehicle on the roadway which caused it to roll. The victim died from his injuries sustained in the crash. Flammond’s blood alcohol content at the time of the wreck was .191.

The investigation was conducted by the Federal Bureau of Investigation and the Rosebud Sioux Tribe Law Enforcement Services. The case is being prosecuted by Assistant U.S. Attorney Tim Maher.

A presentence investigation was ordered. A sentencing date has not been set. The defendant was remanded to the custody of the U.S. Marshal pending sentencing.
