Two suspects accused of murdering an army reservist on a Kirkwood bike trail pleaded “not guilty” to the charges on Monday, June 9.

Fulton County District Attorney spokesperson Yvette Jones said there was a plea and arraignment hearing Monday morning for Qutravius Palmer and Zion Wainwright.

“Defense attorneys for the two defendants waived formal arraignment and entered not guilty pleas,” Jones said. “The case will be placed on the August 2014 trial calendar. However, an exact trial date has not been set.”

Both are accused of murdering X’avier Arnold during a robbery attempt in December. The murder outraged the community, and there are still many signs in Kirkwood with a simple “X”on them, displayed in solidarity with Arnold’s family.

Arnold’s two friends told investigators that on Dec. 26 they were walking a bike trail near Pullman Yard when they noticed the two suspects following them. When they turned to confront the suspects, one of them pulled out a gun. Arnold fought back. Witnesses and police allege that Wainright fatally shot Arnold in the back of the head.

Jones said the suspects remain in custody.
