Mercedes Stafford is the former president of the Cincinnati Roller Girls. She skated under the name 'Sadistic Sadie,' and won the 2009 Most Valuable Skater award. She was the Women's Flat Track Derby Association's Featured Skater in May 2010. On June 1, she pleaded guilty to airline-ticket wire fraud. Between 2007 and 2009, while she worked for United Airlines, she stole $400,000 worth of airline tickets, then sold them to her friends and family, a group that included some roller-derby folks, and pocketed around $50,000. After her plea, the WFTDA removed her Featured Skater page from their site.
