PROVIDENCE, R.I. (AP) _ One of several people charged as part of a federal investigation into an alleged $10 million kickback scheme targeting the U.S. Navy is scheduled to change his plea to guilty on tax evasion charges.  
Ralph Mariano Jr., of North Providence, is scheduled to appear in U.S. District Court in Providence Wednesday.
Mariano's son, Ralph M. Mariano, a former Navy employee, is accused of being the ringleader of the scheme, allegedly using Navy contractors to funnel government money back to himself, his father and others.
Mariano Jr. is accused of failing to pay taxes on the money he received. He is in his 80s.
The younger Mariano and his girlfriend, Mary O'Rourke, are scheduled to go to trial next month.  
Three other men have already pleaded guilty in the case.
