A tentative trial date has been set for the man charged with murdering Lyon Village resident Carl Diener.

Roger K. Clark III is facing a first degree murder charge in connection with the 2009 slaying of Diener. The 57-year-old Diener was found lying on a Clarendon side street in the early morning of Dec. 29, 2009. He was pronounced dead on the scene.

After a year and a half investigation, police arrested Clark and another man in June. The other suspect has since been released, while Clark faces a jury trial that’s currently scheduled to begin on Jan. 9, 2012.

The trial is expected to last at least four days, according to Diener’s sister.
