A federal investigation in Chicago of one of the nation's largest red-light camera programs has led to charges against the former CEO of a Phoenix-based company.

The U.S. Attorney's Office said Wednesday that former Redflex Traffic Systems Inc. executive Karen Finley faces multiple corruption charges.

Prosecutors say she provided a retired Chicago official around $570,000 in cash and other benefits for inside information helping Redflex land city contracts that grew to $124 million in value.

The ex-city official, John Bills, was indicted in May. His attorney has said Bills never took bribes and is merely a "scapegoat."

Finley lives in Cave Creek, Arizona. She worked at Redflex for more than a decade until 2013. There's no publicly available telephone number for Finley. A message seeking comment from Redflex wasn't returned.
