A Missouri woman who prosecutors say played a central role in a scheme to buy more than 300 vehicles with phony titles and improperly export them has pleaded guilty to federal wire fraud.

Patrice Robertson pleaded guilty Tuesday as part of a plea agreement. She ran the vehicle brokerage in Chillicothe, Mo., that improperly bought the vehicles for export.

Earlier this month, a former Omaha car salesman and the owner of a Kansas trucking company were both charged with 11 counts of wire fraud and one conspiracy charge.

Authorities say the three purchased roughly 342 vehicles fraudulently from at least six different dealerships in Nebraska, Kansas, Missouri and Ohio.

The Nebraska State Patrol launched the investigation in 2006 after several Hummers ostensibly to local buyers weren’t registered in the state.
