Two former Deadwood Mountain Grand employees are accused of embezzling about $13,000 from the resort.
Last week, one of them, Amanda Greenwald, 31, pled guilty. The other woman charged, Toni Sales, 38, has pled not guilty.
Prosecutors say the two worked in the office at the gaming resort and were transferring fictitious canceled show refunds to their own accounts.
Their alleged scam started last January and continued through August when they were caught.
Greenwald will be sentenced next month.
