Following a fatal officer-involved shooting, video from the scene and audio from police dispatch and a witness have been released. Each element paints a picture of what happened on Morgan Avenue just west of Theater Drive on the evening of Oct. 28.

Authorities said Terry Chanley, 45, was killed after crashing his Jeep Wrangler into a utility pole. Evansville Police Capt. Andy Chandler said Chanley aggressively approached the officer, who has not been identified, with a hammer before being shot. Police say witness accounts and evidence confirm this description of events, but one eyewitness account recorded during a call to 911 conflicts with this claim. Police say that witness has not yet made an official statement.

Here's what each element reveals:

Officer says he saw a gun under Terry Chanley after the shooting

The selection of audio begins with intermittent pieces of conversation between dispatch and officers, documenting the involved officer responding to the scene of the crash. Police later said the officer arrived on the scene at 6:28 p.m. A frantic voice is heard in the background after this. Minutes later, dispatch confirms a shooting.

"They're advising shots fired."

A request for a sergeant is made to respond to the scene followed by a status check. Dispatch says the suspect is down. Authorities head to the scene, hearing from an officer that the subject is on the ground with a gun underneath his stomach and still moving.

Police head to the scene to secure the area.

Eyewitness says Chanley's hands were on his head during the shooting

"I just witnessed a cop shoot a guy in the chest," Vincent Owen said in a 911 call.

During the call, Owen tells dispatch that Chanley had his hands on his head and "didn't have no gun or nothing." He tells them that about five shots were fired.

Owen said he approached the officer after the shooting, but that the officer told him to get in his car and leave the scene. It's unclear where Owen was when he witnessed the shooting.

Officer fired shots about a minute after arriving on the scene

Police released dashcam video of the shooting, blurring the identities of witnesses and the involved officer. Audio from the video is very faint and hard to make out what those on camera are saying.

In the video, we see a man in a dark jacket approach the officer, who then gets out of his vehicle to approach the scene of the crash. Alongside a white SUV obstructing the crashed Jeep Wrangler is another unidentified man in a white long-sleeved shirt on the shoulder of Morgan Avenue.

The officer follows the man in the dark jacket on the street side of the vehicle, joining the other man at the front of the vehicle. What takes place then is largely obscured by the SUV until two other unidentified men run to the middle of the street and the man in the white shirt retreats to the shoulder by the SUV.

About a minute after arriving on the scene, the sound of gunfire is heard from the officer's dashcam, and the two men run across the street and the man in white, past the officer's car. After a third shot is fired, the officer comes into frame and fires another shot. At this point, we see Chanley fall to the ground.

A fire truck responds to the scene within seconds while the officer keeps his gun drawn.

Officer told Chanley to show his hands before shooting

Police released bodycam video of the shooting, blurring the identities of witnesses and the involved officer. Still, the video provides the clearest picture of the shooting so far.

The officer begins recording the bodycam video just before arriving on scene. He arrives, greets the man and walks past a white SUV to see a white car with its driver's door open and the crashed Jeep Wrangler on the road's shoulder.

"How we doing sir, you doing alright?" the officer asks a man sitting inside the Wrangler.

The man inside the Wrangler is Chanley. He tells the officer he doesn't have his driver's license. The officer then turns on his flashlight, revealing Chanley with a cigarette in his mouth and the airbag deployed. Chanley appears casual, almost peaceful, despite being involved in a car crash. He then reaches over to the passenger's side of the car, startling the officer.

"What are you reaching for?" the officer says. "Woah, woah, woah. Let me see your hands."

The officer draws his gun.

"Let me see your hands!"

He asks Chanley to step of the Wrangler. In the span of just two seconds, the officer screams, we see Chanley move in the car, and the officer shoots twice.

"Shots fired! Shots fired!" he yells, while firing another round.

"Let me see your hands! Shots fired!" the officer calls out, repeating it over and over again, louder each time as his voice breaks.

The officer becomes emotional, swearing and breathing heavily, raising his gun back towards Chanley as fire and police crews are dispatched to the scene.
