A federal judge has declared a mistrial in the bid-rigging trial of a Detroit contractor whose business flourished when Kwame Kilpatrick was mayor.
Bobby Ferguson was on trial on accusations he participated in a scheme to rig bids on a housing project to benefit his business.
Judge David Lawson acted Tuesday afternoon after jurors reported they were deadlocked. The government says it's disappointed and will retry the case.
Ferguson also was accused of money laundering and illegally possessing firearms. He's a former felon barred from having guns.
Ferguson's lawyers say the government's case is built largely through shady witnesses who made plea deals and agreed to testify.
Ferguson also faces a corruption trial in September with Kilpatrick and Kilpatrick's father, Bernard.
Kwame Kilpatrick quit the mayor's office in 2008.
