A criminal investigator with the U-S Department of State is scheduled to make a first court appearance in Waukesha County next week.  Fifty-three-year-old David Scharlat faces three charges of felony rape.  Scharlat is accused of forcing three women to have sexual contact with him.  One woman says he warned her he was a federal agent when she tried to break up with him.  The State Department hasn’t said if he still has his job.  If convicted, the 17-year federal employee could face up to 150 years in prison.
