Jamilla Humphrey has been missing from her NSW home for seven weeks, last seen near the tip of Cape York, Queensland, having made two crossings of the Jardine River in a short space of time before her poorly equipped vehicle was discovered abandoned on August 24.

The 52-year-old left barely a trace of her movements as she made an almost unfathomable drive from Toukley, NSW, to the Tip in a two-wheel-drive Mitsubishi van on some of the toughest roads in the country.

Vanishing with barely a trace, there has also been very little chat about the matter since Queensland Police called off the search for her on September 6.

Talk remains that Ms Humphrey has twice “disappeared” before, once in Alice Springs and also in the Grampians, and reappeared with a new identity. There is no confirmation of that. Her erratic behaviour, highlighted by the more than 3200km drive she had to make in a few days to get to her final destination, also raises more questions than gives answers.

At the time the search was suspended, police said in a statement the large-scale search had been abandoned on the basis of new information, but did not specify what it was that led to the decision.

“The suspension of the search is subject to additional information or intelligence being received regarding her disappearance,” the statement said.

Queensland Police Service dispelled the speculation of a body being found in a community.

“There has been no body found,” a police spokesperson said.

“Local police have advised that there are a lot of rumours going around but no body has been found.”

But search expert Chris D’Arcy of Search Dogs Sydney, says the mystery could have been far less had the search for Ms Humphrey utilised the professional resources available.

Mr D’Arcy has worked on 116 missing persons cases and is promoting a petition in NSW calling for an overhaul of how authorities approach search and rescue operations. He will host the first ever Missing Persons Symposium on November 23 and 24 and his petition can be found on the Search Dogs Sydney and Leave A Light On Inc Facebook pages.

“Given the remoteness of the location, police could have flown in expert trailing dogs as well as utilising drones equipped with state of the art artificial intelligence to search the vast areas,’’ he said.

“The dogs could have picked up a scent to guide the searchers to a direction of travel whilst the drones would be able to cover vast areas whilst crews remained safe.

“These resources could have been flown in quite easily to such a remote location,’’ he added.

Mr D’Arcy played down the possibility that Ms Humphrey had gone missing deliberately.

“Given the remoteness of her vehicle it is doubtful that she went missing on purpose whereby all possible resources should have been deployed.’’

The Search Dogs Sydney teams and those trained by them are certified in Lost Persons Behaviour and would have provided additional assistance in locating the missing person.

“However, many police do not possess this training provided by Search Dogs Sydney’s instructors,’’ he said.

Jamilla Humphrey was last seen around 1am leaving a home on Moss Avenue on August 20, and on Thursday, August 29, a white Mitsubishi van with NSW registration AE 92 WX – believed to be driven by Ms Humphrey – was located on The Old Telegraph Track, near Jardine River in Cape York.

She is described as Caucasian appearance, fair complexion, about 180cm tall, thin build, and blue eyes. Police believe she now has short, brown hair, and may be wearing dark shorts and a dark t-shirt. Anyone who may have seen Ms Humphrey or has any information that could assist police, is urged to contact police.
