US Attorney Timothy M. O’Shea, Retirement, Wisconsin 2023

MADISON, Wis. – U.S. Attorney Timothy M. O’Shea announced that he is retiring from the federal government after 34 years of service with the U.S. Attorney’s Office for the Western District of Wisconsin.

Mr. O’Shea began his career with the U.S. Attorney’s Office as an intern in January 1991. He was hired as an Assistant U.S. Attorney in the criminal division in August 1991 and served in that role until 2002, when he was appointed Senior Litigation Counsel.

During his career as a federal prosecutor, Mr. O’Shea prosecuted a broad array of federal crimes including money laundering; tax crimes; bank, mail, wire, and credit card fraud; illegal weapons; narcotics; bank robbery; murder, attempted murder, and other violent offenses.

He also had a particular emphasis in computer and intellectual property crimes, specifically trade secret theft, system intrusions, and illegal counterfeit and distribution of copyrighted material. He was the lead prosecutor in United States v. Sinovel, the first and only federal jury trial and conviction of Chinese company for trade secret theft.

The prosecution team recovered more than $58 million in restitution for the victims. Mr. O’Shea was also an experienced appellate advocate, arguing more than 60 cases before the Seventh Circuit Court of Appeals.

As U.S. Attorney, he was considered the chief federal law enforcement officer in the Western District of Wisconsin, responsible for overseeing all federal prosecutions and civil litigation involving the United States within the district.

Following U.S. Attorney O’Shea’s retirement, Assistant U.S. Attorney Chadwick Elgersma will serve as the Acting U.S. Attorney until a U.S. Attorney is formally nominated by the President and confirmed by the U.S. Senate.
