Closing arguments set for Wednesday in Balfour trial

Prosecutors saved their biggest evidence for Tuesday, the last day of testimony in the trial of William Balfour

That evidence?  A key ring.  Chicago detective Tom Kelly testified Balfour carried those keys with him when he was arrested  just hours after the Hudson family murders in October 2008.

One of those keys matched Jason Hudson's white SUV, the one found abandoned on Chicago’s west side after the murders.  The body of Julian King was inside.

But police didn’t test the keys until three years after the murders.   And they weren't recorded in the evidence log at the time. 

“The defense pointed out that the police detective didn't actually inventory the keys until sometime in late November, about a month later.  I expect tomorrow in closing arguments they'll be making something big about that,” said legal analyst Terry Sullivan. 

And in contrast to more than a week of testimony by more than 80 state witnesses, the defense was short.  Just two detectives were called, lasting 20 minutes total.

During the defense’s case, Detective Greg Jacobson admitted he made a mistake on his report, written right after the murders - A 12 hour time difference on when evidence was found.

The one voice missing from this trial was that of Balfour, who didn't take the stand in his own defense.

Closing arguments are scheduled to begin at 11 a.m. Wednesday.
