PHOENIX — Newly obtained video and crime scene photos from the night David Denogean was murdered, provides a new look into Phoenix police's investigation.
David, a beloved Valley track coach, was shot and killed while walking his dog on Black Friday in 2022
Not long after the 30-year-old's murder, Silent Witness released part of the surveillance video obtained from nearby businesses. It showed a figure run out of the shadows, stand in front of David, and then hold up a gun.

Nearly four years later, we're getting a first look behind the crime scene tape. The ABC15 Investigators received the full surveillance videos, body camera footage, and crime scene photos from the case.
This release comes close to a year after the police report in David's case showed detectives had zeroed in on a suspect, but no arrests had been made.
While the Denogean family didn't want to review all records, loved ones wanted the newly obtained video and photos to be seen.
They hope speaking out will motivate someone to come forward and help their family get answers.
A LOOK INSIDE THE CRIME SCENE
"This person didn't just murder David, you took somebody that was important to a lot of people," said David's dad Frank Denogean.
Nearly four years after their son was shot and killed, the David's parents have more questions than ever.
ABC15 described the key parts of the records received by Phoenix police to David's family, including pictures of evidence in the case.
Body camera video showed a chaotic scene near 12th Street and Maryland just moments after the shooting on November 25, 2022.
Witnesses who were eating nearby at Feeney's Restaurant and Bar are seen on camera giving police descriptions of the shooter and even detailing a sedan some thought could be involved.
Police quickly gathered surveillance video from nearby businesses. In one clip, the gunman can be heard firing his gun more than 10 times before running off.
Surveillance cameras catch the person running from the scene with David's dog, Evie, not far behind. After running out of frame, the Denogean family said Evie made it back to David's home without her collar or leash.
This was the first sign for loved ones that something had happened to David.
On scene, police can be seen finding shell casings and even a piece of evidence that stood out to officers.
Officer 1: "It looks almost like a handload."
Officer 2: "I've never seen a purple bullet."
The exchange can be heard on body camera video, and the bullet was photographed multiple times.
A grainy photo of a car, which hadn't been shared publicly, was also included in the records release.
ONLY SUSPECT BEHIND BARS
"Yeah, I think it's hard to believe that nobody knows," said Frank.
The Denogeans feel someone in the community has information that could help the case.
For years, they have expressed frustration with the communication from Phoenix police.
In September 2025, ABC15 also obtained the police report in David’s case.
It showed investigators quickly focused on a suspect, noticing similarities between David’s fatal shooting and another that happened less than 24 hours later at a north Phoenix gas station.
The shooter in that case, a now 33-year-old man who was arrested on scene.
"Well, it was very surprising," said David's mom Judy Denogean. "Because, for one thing, they could have told us the next day. And we've gone all this time, you know, thinking that guy was still out there."
The Denoegean family learned about a possible suspect when local media obtained the report, which also outlined why police believed there could be a connection between the two shooting.
"What if this is the guy?" said Frank. "You know? Are you satisfied that he's in prison already for another crime."
The person police have called their only suspect took a plea deal in 2024, agreeing to spend 25 years behind bars. He was only convicted in the gas station shooting and has never been charged in David's case.
Frank said he wants more done by police to ensure his son gets justice.
"I don't know if they've ever got started, it seems like, but now we're at a dead end," said Frank.
With little answers, the Denogeans wanted to know more about the investigation. Their questions included: did detectives follow-up on that purple bullet and what about the car seen in those photos?
"So, you have all this. Now what? said Frank. "You have a suspect. What have you done or not done to see if this is the guy?"
ANSWERS FROM POLICE
ABC15 took those questions and more to Phoenix police, who sent a statement in response.
"Video surveillance cameras captured a small 4dr sedan, light in color (possibly gray), in the area at the time of Mr. Denogean's murder. Based on the vehicle's movements, it is a vehicle of interest in the homicide. The video was not clear enough to be able to identify the make/model of the vehicle, and no plate was captured. The vehicle [the suspect] used in the murder on the following day is similar, but we cannot definitively say it is the same.
The purple bullet found on scene was tested for fingerprints and DNA, and unfortunately, it did not result in a profile."
The agency also said while the case is active and being worked, it is considered a cold case because no new leads have been located.
Phoenix police said they would also have a sergeant follow up with David's family.
"I see the news and I see these families that ten, fifteen, twenty years has passed, and they finally get something or some sort of resolution," said Judy. "And I just tell my husband, is that going to happen to us?"
David's parents are hoping to meet soon with investigators.
ABC15 was also told there are new supplements that have been added to the police report in David's case. Our team has requested those additions.
As for the man already behind bars, police said he is still considered a suspect. Court records show he has been charged in multiple cases while in prison, at least one includes allegations of assaulting a corrections officer.
REMEMBERING DAVID
There is a $20,000 Silent Witness reward in the case.
The Denogean family holds multiple events in honor of David each year.
In November, on Black Friday, they will hold their yearly vigil to help raise awareness about the case.
Around Christmas, loved ones also hold a toy drive in David's honor to give back to the community.
