In March 2015 John Beckenridge and his stepson Mike Zhao-Beckenridge disappeared. The car they were travelling was discovered at the base of a Catlins cliff in Southland but no bodies were found, and the Police investigation continues as a missing persons case.
Loved ones searching for missing teen Mike Zhao-Beckenridge have turned to celebrity psychics in a bid to shed light on his disappearance.
Last Tuesday marked the third anniversary since John Beckenridge picked up his then 11-year-old stepson from an Invercargill school, breaking a court order, and disappeared.
Beckenridge's vehicle waslater found in the surf off the Southland coast, but there was no sign of bodies in the remains of the 4WD and police told the Herald on Sunday before the anniversary the investigation remains active.
In the book, Cruickshank writes how Mike's mother had been persistent in trying to get him to do a full reading, including approaching him at his motel and attending several of his shows.
Russell said his partner had talked to many psychics "to make sure Mike hadn't passed on".
"The psychics said Mike was living on an island," he said.
In her first public comment since Mike's disappearance, Lu told the Herald on Sunday last weekend she believed her son was alive and there was "not a single day I don't think of him. I love him deeply."
The family's extensive search for answers has seen them employ private investigator Mark Templeman, who has worked on high profile missing persons cases in New Zealand and overseas.
Russell revealed last weekend they had spent more than $150,000 on the search, including checking out a possible sighting of Mike and Beckenridge on Gili Air Island, Indonesia.
Police investigating the case have stated inquiries were "ongoing and this remains an active investigation".
"During the course of this investigation a variety of information has been received from the public and this information has been thoroughly assessed and investigated by the inquiry team," police said in a statement.
"As this inquiry remains an active police investigation the coroner's inquiry is on hold."
