DETROIT -

Former head of economic development at Wayne County, Turkia Mullin, gave the county a check Thursday, as she promised.

Mullin accepted a $200,000 severance package when she left the job to take the CEO position at Detroit Metro Airport. After taxes, Mullin's payback to the county was roughly $135,000.

Now, Wayne County commissioners want to know why the severance was given to Mullin, who exactly signed off on it and was there a move to cover it up?

The Wayne County commissioners said there is a letter document that appears to be a phony contract meant to cover for Mullin. They held a meeting Thursday to discuss the letter.

County Executive Robert Ficano said assistant county executive Azzam Elder and corporate councilwoman Marianne Talon were responsible for the letter, and both have been suspended for 30 days.

"There are going to be some trust issues when those individuals come back," said commission chairman Gary Woronchak. "It's going to take time to rebuild that trust."

Ficano's office said Elder and Talon will not be fired.
