The Danbury City Council has agreed to a  separation agreement with the City's Finance Director, who has been on paid leave for more than a month.  No members commented on the agreement with David St Hilaire.  He worked for Danbury for 15 years and was one of the highest paid employees in the City.  Assistant Finance Director Dan Garrick has been leading the department since St Hilaire was placed on paid leave 6 weeks ago.  Those involved say the separation negotiations are confidential and no one would be commenting.  The Council went into executive session at the end of their meeting Wednesday and voted to approve the agreement without public discussion.
