Also, Kathi Bohache, former employee of parking garage company PMI, was indicted for defrauding the city of Dayton for about $250,000.
Each face up to 10 years in jail and up to $20,000 in fines.
Heck said Slagle defrauded Pickrel, Schaeffer and Ebeling — the ninth-largest law firm in the Dayton area, according to Dayton Business Journal research — between February 1999 and December 2001. Slagle, who left the firm in the summer of 2001 as a partner, would ask his clients to pay him personally and pocket the money.
After leaving the firm, he opened his own practice in Hillsboro.
Assistant Prosecutor George Patricoff said Slagle was to be arraigned at 4 p.m. Thursday.
Bohache is still at-large and a warrant has been issued for her arrest, Heck said. He added that the city of Dayton was reimbursed by PMI for the approximately $250,000 she took between 2002 and 2004.
