A third person has been charged in relation to the disappearance and alleged murder of Bundaberg teenager Pheobe Bishop.

Kieren Daniel Mittelheuser, aged 30, was taken into custody in Bundaberg West around 7 pm yesterday. He now faces charges of being an accessory after the fact to murder.

Police alleged he used Bishop’s phone to interfere with the investigation.

The man will face Bundaberg Magistrates Court later today.

Bishop’s roommates, 34-year-old James Wood and his 33-year-old partner Tanika Bromley, have been accused of her murder and tampering with her body.

The pair will face court in August.

Bishop disappeared on May 15 after failing to board a flight from Bundaberg Airport to visit her boyfriend in Western Australia. 

Extensive searches and public appeals failed to yield any results for several weeks until police made a breakthrough on June 6.

Crews had found human remains near the Good Night Scrub National Park, about an hour away from Bishop’s home in Gin Gin.

Those remains were later confirmed to belong to Bishop. 

As part of the investigation, three crime scenes have been identified including the location where the remains were discovered, the home in Gin Gin that Bishop shared with her roommates, and her roommate’s grey Hyundai IX35.

Community vigils were held for the 17-year-old in Gin Gin and Bundaberg in June.

Her mother, Kylie Johnson, said Bishop always “sung her own tune”.

“She lived to the fullest,” she told the crowd at the vigil in Gin Gin.

“She loved the people that she loved to every extent of the earth, and she was 200 per cent invested in the people that she loved.

“And that is what we need to hang on to and remind ourselves of it every day.”

Bishop’s sister Kaylea Bishop said 17 years was “never enough” life.

”But in the short 17 years that she was with us, God, she gave us a run for our bloody money,” she said alongside her mum at the vigil.

“But that’s just the way Pheobe was. But she was loyal to the core to everybody she loved, respected and valued in her life.”

Police continue to appeal for any information in relation to Bishop or the movement of a grey Hyundai IX35 between May 15 to 18 in the greater Gin Gin area.
