PITTSBURGH — Federal prosecutors in Pittsburgh want an Indiana man sent to prison for helping send millions of illegal spam messages to U.S. and international cell phones and computers.

Phillip Fleitz, 31, of Indianapolis is scheduled for sentencing today. Two other men in the same scheme have received probation, but federal prosecutors want Fleitz to serve more than two years in prison. They say he was already on probation for driving under the influence when he was charged in the spamming scheme and has failed drug tests since his arrest.

Fleitz’s attorney contends prison would be overkill in light of the other sentences.
