Zachary Lambert and John Thurman pleaded not guilty to charges of one count each of aggravated robbery and assault in Sharp County Circuit Court June 3.
Both men will be back in court June 17 for a jury trial on the charges.
Lambert and Thurman are charged with committing an armed robbery and Lambert with allegedly firing shots at several persons Jan. 8.
Lambert's father, 3rd Judicial District Prosecuting Attorney Stewart Lambert, was charged in March with hindering apprehension or prosecution when he ordered officers off his property when they pursued the two men to his house and attempted to arrest them following the incident. He will appear in court June 17 for a pretrial hearing.
Special Judge Floyd Lofton of Maumelle and Special Prosecutor Will Feland of Cabot traveled to Sharp County to hear the pleadings. No other cases were on the docket.
Lofton instructed Sharp County Clerk Tommy Estes to poll 200 additional jurors for the trial.
Zachary Lambert's attorney, Tom Thompson, filed a waiver of arraignment on Lambert's behalf, which allowed him to represent Lambert without his presence.
According to the affidavit for warrant of arrest for Thurman, he gave a statement to the Arkansas State Police Jan. 9 in which he confessed he and Lambert had "come up with a plan to rob Justin Clark of Cherokee Village of drugs they suspected he had."
