TUCSON, AZ (Tucson News Now) - Tucson News Now obtained the radio transmissions between Tucson police officers during an aggravated assault from Aug.17, 2015.
The tape starts off with two people asking about a call.
"Did you ever take care of that exposure call?" asked one unidentifiable person over the radio.
"10-4 Is he back?" responded another.
In the early morning hours of August 18 police said Daniel Nelson showed up to a Circle K twice wearing nothing. At the convenience store, police said, he got into a fight with officer.
After the fight, Nelson was taken to St Josephs' Hospital where police said things took a dangerous turn. Several minutes into the radio transmissions, there is silence for about four seconds.
Then a woman's voice can be heard. "I see you are trying to transmit," she said.
Tucson Police Officer Dan Lucas, talked Tucson News Now through the tape and said silence being transmitted is not always good.
"An officer, they weren't aware at that time which officer, came up on the air and they weren't exactly sure why that officer came up on the air," he said.
Lucas said those few seconds can turn into very scary moments, especially for responding officers.
"We don't know what we are coming to," he said "It could be something as simple as they keyed a mic or it could be something like they are in a fight for their life."
Then less than a minute later this comes over the radio. "We just got a call in the detainee just stole the officer's gun they are going to be on the first floor."
During the next few minutes, several officers could be heard responding. And then the woman comes back over the frequency.
"We are going to need crime scene back here they can meet us at the emergency room," she said.
Lucas explained hearing crime scene respond to a incident actually gives officers a sense of relief.
"From an officers standpoint the investigation or situation has now turned to a investigative standpoint so the danger has been eliminated at that point," said Lucas.
