Hauke was a longtime financial columnist for IBJ, but the paper dropped his column after the legal problems arose.
The investigation showed that Hauke had invested millions of dollars from the hedge fund into Michigan real estate without telling clients, and the holdings ended up nearly worthless.
The two live in Indianapolis with Keenan Hauke and Sarah Mackey’s three children.
Hauke said in his petition that he fired Mackey a few weeks after discovering the relationship.
Sarah Mackey, in an interview, strongly disputed her ex-husband’s version of events.
Larry Mackey issued a statement through a spokesman denying Hauke’s claims generally. Keenan and Sarah Hauke separated in early 2011, while authorities were hedge fund.
Hauke outlined his allegations in a 10-page petition filed in U. Sarah Hauke filed for divorce in 2011, and the divorce was finalized that December.
