The jury in State Department special agent Christopher Deedy’s murder trial ended their first full day of deliberations without reaching a verdict Monday.

They are scheduled to resume deliberations Tuesday at 9 a.m.

The panel of eight men and four women is faced with deciding whether Deedy should be found guilty of murder or acquitted for shooting Kollin Elderts at the Kuhio Avenue McDonald’s restaurant early Nov. 5, 2011.

The jury deliberated for more than two hours Thursday afternoon before recessing for the Admission Day weekend. Today, they started at about 9:30 a.m. and deliberated with a break for lunch until about 4 p.m.

Deedy, 29, of Arlington, Va., who was here to provide security for the Asia-Pacific Economic Cooperation conference, is charged with shooting Elderts, 23, of Kailua, without justification.

Deedy’s defense is that he fired his 9 mm Glock to protect himself and a friend.

The high-profile trial included 20 days of testimony over a span of five weeks.
