ST. PAUL — Federal prosecutors say a Twin Cities attorney was involved in a scheme to rip off car insurance companies with false medical claims.

William Kyle Sutor, 37, was charged Monday, Dec. 30, in U.S. District Court with conspiracy to commit health care fraud.

Prosecutors used a charging document called “an information,” rather than convening a grand jury. That typically means the defendant has agreed in advance that he will plead guilty.

A court date has not yet been set, but the U.S. attorney’s office said a plea agreement will be filed soon.

According to the information, the St. Louis Park attorney and unnamed others conspired to defraud auto insurers on policies provided pursuant to the state’s no-fault insurance law.

Under that law, Minnesota insurers must provide at least $40,000 in personal injury protection on their auto policies. Clients hurt in a car crash can get their medical bills and other related expenses paid for, whether the crash was their fault or not.

The charging document says the conspiracy took place between March 2015 and 2017 but does not spell out what Sutor is alleged to have done.

His attorney did not return a request for comment.

It’s not clear whether the case stems from the same investigation that since December 2016 has produced dozens of prosecutions against chiropractors and the “runners” they hired to drum up fraudulent business.

In those cases, prosecutors proved that chiropractors made millions of dollars off false medical claims from car crashes, likely resulting in higher insurance rates for all drivers.
