MILWAUKEE, Wis. (WTAQ) - A former vice president of Milwaukee’s Koss Corporation might plead insanity to new federal charges that she embezzled $31 million. Michael Hart says he’ll show that mental health issues played a major role in what Sue Sachdeva did. A federal grand jury indicted the 46-year-old Sachdeva Wednesday. She was originally accused of embezzling $4.5 million from Koss. But the maker of stereo headphones later discovered that $31 million had been taken since 2005. And Sachdeva was accused Wednesday of taking it all for lavish clothes, cars, vacations, and remodeling work at her home in Mequon. The indictment said she wired $1.6 million in 3 transactions last September alone. Authorities said it all came to light when American Express told Koss that Sachdeva transferred company funds to pay one of her credit card bills. Her new indictment charges her with 6 counts of wire fraud.
