The jury deliberated Monday evening and most of Tuesday afternoon. Jurors sent a note to the judge and the attorney 4 p.m. Tuesday, saying they have questions about the legal concepts, "reasonable doubt" and "burden of proof" in the case.
The judge gave them additional instructions, and after a full day of deliberations, they were still not able to reach a verdict.
Jurors are deliberating the fate of Ronald Evans, Byron Howard and Aaron Dexter. All three defendants are charged with kidnapping, beating and shooting a Home Depot store manager after a botched robbery attempt.
Prosecutors say the defendants handcuffed the victim, shot him through the hand and locked him in a rental truck. Two men testified against the defendants in exchange for lighter sentences. One defendant said the men were willing to shoot a police officer if one stopped them.
The defense says the men are not credible because they agreed to a deal with prosecutors. Each of the defendants face five felony charges.
The jury will continue to deliberate on Wednesday.
