Sources say that a key figure in the case of Rod Blagojevich -- Christopher Kelly -- was found dead this morning.
The news comes just days after Kelly pleaded guilty to a scheme involving $8.5 million in fraud at O'Hare airport.
He was to report to jail by Friday and was on a curfew, which he agreed to, until he turned himself into court.
On the day he pleaded guilty, Kelly, 51, told a judge he'd be remiss if he didn't say he felt pressures in his life. The onetime adviser to Blagojevich had been hit with three federal indictments and refused to flip on his friend.
He faced nearly eight years in prison from two guilty pleas.
Update: A law enforcement source is saying Kelly died of an aspirin overdose.
