The two men accused of holding the Colfax Avenue RadioShack employee hostage treated the victim "decently," according to the documents.
The released documents say the suspects, Taveuan Williams, 19, and Michael Annan, 23, told the store's manager, 28-year-old Chris Nimerfroh, several times he was not going to be hurt and even apologized to the victim as they were being arrested.
The suspects told the employee he was "leverage to keep the police from coming into the back room of the store."
According to the probable cause statement obtained by 9Wants to Know, the suspects opened fire at Denver Police officers as soon as they saw them, firing at least twice.
Nimerfroh told police Williams and Annan entered the store around 9 a.m. "wearing bandanas over their faces." They were armed.
Court documents say one of the suspects locked the front door and both men ordered the manager around at gunpoint.
"The suspects ordered [Nimerfroh] to place several smart phones, iPhones, gaming systems and other merchandise into duffle bags that the suspects brought with them," the document reads.
They asked for a safe. The store didn't have one. They then ordered Nimerfroh to empty the register where they took $250 to $350.
Nimerfroh was forced into the bathroom. Annan took $5 from the victim and his ID card.
The hostage told police he heard the suspects yell "50" and then heard two "pops," which he described as gunshots. He then told police Annan ran into the bathroom, pointed the gun at him and accused of him of setting off an alarm.
During the six-hour standoff, Nimerfroh told detectives that he and Annan made several phones calls, telling people they were "going to jail."
According to court documents, Williams told an unknown person "he had fired at the cops, he was going to jail for a long time and he was going to die today."
Nimerfroh told police he thought Annan was recently at the store, as the suspect told someone on the phone that he had been "casing" it before the robbery.
Both men are facing several charges, including kidnapping and criminal intent to murder a peace officer.
No one was hurt in the standoff.
