There, he gained extensive experience trying cases before a jury and arguing contested motions on behalf of misdemeanor and felony defendants in the Milwaukee courts. Jason’s criminal defense experience includes representing and defending clients in general misdemeanor and felony cases, including OWI cases.
Embezzlement
In another example of a high-profile case handled by Mr. Laing, he represented a bank being sued by Koss Corporation in connection with an embezzlement by one of Koss’s employees, Sujata Sachdeva, who obtained $17 million of the embezzled funds from Koss’s accounts at the bank. Ms. Sachdeva embezzled a total of $34 million from Koss, which is the ninth largest embezzlement in U.S. history. Koss sought $42 million in damages from the bank, alleging that the bank acted in bad faith under the Uniform Fiduciaries Act by failing to detect the embezzlement. After more than five years of litigation, Koss’s case was dismissed by the trial court on summary judgment, which ruling was subsequently affirmed by the Wisconsin Court of Appeals in 2018 and later affirmed by the Wisconsin Supreme Court in 2019. The bank paid nothing on Koss’s claims. The lead attorney for Koss was Michael J. Avenatti of California.
