Jurors Deliberate 2010 Double Murder

Timothy Herring, 24, is accused of killing a Chicago police detective and a former Chicago Housing Authority officer "execution style"

UPDATE: Jurors did not reach a decision after several hours of deliberations. They're sequestered until 10 a.m. Wednesday.

A Cook County jury on Tuesday afternoon began deliberating the fate of a man accused of killing a Chicago police detective and a former Chicago Housing Authority officer five years ago.

Earlier in the day, the jurors and their alternates again heard a 911 call made shortly after the 2010 slayings allegedly committed by Timothy Herring. The mother of Stephen Peters cried uncontrollably as the sound of two gunshots recorded on that call filled the courtroom.

When the trial began last week, prosecutors said Peters, a former CHA officer, and Michael Flisk, a Chicago police officer, were shot "execution style" by Herring.

Herring, then 19, was charged with two counts of first-degree murder. 

Prosecutors said Herring broke into Peters' car and shot the men on Nov. 26, 2010 after he found out Flisk found fingerprints. They said Herring wanted to avoid returning to prison.

Defense attorney Julie Koehler said prosecutors had no substantial physical evidence linking Herring to the crime. She said those witnesses who are expected to testify against Herring were either motivated by a reward or were saving themselves from an obstruction of justice charge.

Herring had previously been convicted of armed robbery and sentenced to six years in prison but was released on parole a little more than two months before Flisk and Peters were killed.

Both the state and defense made their closing arguments Tuesday before the judge handed the case over to the jury.
