Daniel Johns, the former editor of The Area News and The Daily Advertiser, as well as former Griffith Local Area Commander, Detective Superintendent Michael Rowan are part of a new podcast called The Missing Files.

The pair are joined by actor and video producer Adam Drummond and TV and film editor Matt Olsen.

The podcast's first episode focuses on the disappearance of Jayden Penno-Tompsett, a Newcastle local.

Speaking on brand new true crime podcast, Rachel Penno, Jayden's mother, spoke of her torment at the ongoing lack of answers surrounding her son's case and has called for a coronial inquest into the matter.

Jayden, 22, was on a road trip from Newcastle to Cairns on New Year's Eve in 2017 when he reportedly ran into bushland at Charters Towers after an argument with a travelling partner and was never seen again.

In the most comprehensive public examination of the case yet, The Missing Files Podcast speaks with Jayden's family, some of Jayden's closest mates and seasoned police officers in a bid to uncover new leads in the probe.

In episode one of the four-part series, released this month, Ms Penno spoke of the pain she had endured since her son's disappearance and urged authorities to look more closely at a mysterious property near where Jayden disappeared on the outskirts of Charters Towers.

"There's a house there, a property, and it needs to be searched but nothing has been done," Ms Penno said.

She said she remained angry at Jayden's travelling companion Lucas Tattersall for not reporting him missing earlier. Jayden wasn't reported missing until January 4, 2018, four days after he and Mr Tattersall parted ways.

"There's been so many different things said: the most recent one was that he is in a dungeon and then there's others, like he was thrown off a cliff or that he was dismembered and acid was used," she said.

"It's so difficult to hear that and I just want my boy home."

She said Christmas and the anniversary of Jayden's disappearance were particularly difficult times.

Speaking on The Missing Files Podcast, Jayden's best friend Jayson Hungerford said he feared Jayden may have stumbled onto a nearby property and, in a heightened state of emotion, been killed during an altercation with a property owner.

Other theories examined by the podcast include speculation Jayden was killed by a bikie gang over drug debt; committed suicide in a remote location; changed identities and fled to start a new life; or was the victim of a roaming serial killer on the notorious Flinders Highway, colloquially known as the "Highway Of Death".

Mr Drummond is the podcast's producer and narrator and said the team, including Mr Johns and Mr Rowan, were determined to shed new light on the fascinating cold case.

"Jayden's loved ones have been subjected to unimaginable pain for three years now and we hope by keeping this case in the public eye, we can spark a lead and a breakthrough in the case," Mr Drummond said.
