CHICAGO (CBS) — A contractor has been convicted of paying nearly $100,000 in bribes to former Markham Mayor David Webb Jr. to guarantee work from the south suburb.

A jury found Michael Jarigese and his business, Tower Contracting, guilty of nine counts of honest services wire fraud and one count of federal program bribery.

Webb previously pleaded guilty to corruption charges. During his testimony at Jarigese’s trial, Webb said Jarigese gave him several bribes in coffee cups filled with cash during meetings in his city hall office.

Federal prosecutors said, as part of the scheme, Webb helped Tower Contracting keep business with the city, and obtain new contracts, including a $3.4 million renovation of Rosener Park, and a $15 million renovation of a senior living center bearing Webb’s name.
