The Circuit Court jury in State Department special agent Christopher Deedy’s murder trial has completed its second full day of deliberations without reaching a verdict, court officials said at 4 p.m. Tuesday.

The panel deliberated for about two hours Thursday afternoon after closing arguments and a full day Monday and today. The jury of eight men and four women are scheduled to return Wednesday morning.

Deedy, 29, who was here for the Asia-Pacific Economic Cooperation conference, is charged with murdering Kollin Elderts, 23, of Kailua, early Nov. 5, 2011 at the McDonald’s Kuhio Avenue restaurant.

The second-degree murder charge carries a mandatory life term with possibility of parole.

The jury does not have the option of returning a conviction on a lesser charge of manslaughter, which carries a maximum 20-year prison term.

The jury sat through 20 days of testimony during a trial spanning five weeks in Circuit Judge Karen Ahn’s courtroom.

Deedy, of Arlington, Va., is accused of firing his Glock 9 mm and fatally shooting the unarmed Elderts without justification. Deedy’s lawyers contend the agent fired in self defense.
