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

The shock development comes only days after the 17-year-old was laid to rest in a private funeral.

Police said on Wednesday that a 30-year-old had been charged.

They will allege Kieren Daniel Mittelheuser used Bishop’s mobile phone to interfere with the investigation.

“Following extensive investigations, police arrested the man shortly after 7pm last night in Bundaberg West,” police said.

“(He) has been charged with two counts of accessory after the fact to murder.”

According to court reports, Mittelheuser is also facing charges of unlicensed driving, fraud, breach of bail and drug possession.

He is due to appear before Bundaberg Magistrates Court on Wednesday.

Bishop was last seen on May 15, when she was alleged to have been dropped off at Bundaberg Airport by her housemates James Wood, 34, and Tanika Bromley, 33.

She was planning to fly to Perth to spend time with her boyfriend but failed to check in.

Crime scenes were initially declared at the home Bishop shared with Wood and Bromley in Gin Gin, and also in a car the pair said they had used to drop the teen off at the airport.

Weeks after her disappearance, Bishop’s remains were found following a search of an area near Good Night Scrub National Park.

Wood and Bromley were arrested on June 5 and each charged with one count of murder and two counts of interfering with a corpse.

They are expected to face court again in August.
