Jay Slater: Suspicious details of last known location REVEALED - 'It's like his phone was thrown!'

The Guardia Civil has called off the search for the teen after scouring through mountainous terrain; enlisting helicopters, drones, specialist dogs and volunteer experts to help assist in the hunt.

Speaking to GB News, journalist Nick Pisa revealed that "momentum still seems to be growing" in both Tenerife and the UK regarding Slater's disappearance, but his own leading theory is that he "has been overcome by tiredness, exhaustion, dehydration, and is probably somewhere up on that mountain".

In the latest development into the investigation, forensic teams have returned to the Airbnb where Slater spent his last night with two other British men, before going missing.

Discussing the development of the men who rented the accommodation the night Slater stayed there, Pisa stressed that the "police have deemed this gentleman, and another who hasn't yet been identified as irrelevant to the case", and the men had informed sources close to Pisa that he "left the house alive".

Pisa revealed: "The police left it as just as I arrived, and they were taking off forensic-style dust covers on their shoes.

"I approached the police officer and I asked him if he could tell me what he'd been doing and whether it was connected to the investigation. He said it was, but he couldn't tell me anything else because it was covered by judicial secrecy."

Revealing another detail in the search for Slater in the mountainous terrain, Pisa said he had spoken to a man who had "found a pair of sunglasses" on the gorge and had handed them to the police.

Pisa explained: "I've now spoken to an ex-British Army officer who found some sunglasses up there. He was asked not to put them in a plastic bag because of humidity, but to wrap them up in tissue paper, which he did.

"He handed them in and he had to give DNA and his fingerprints. The question is, are they connected to Jay?"

When asked by host Bev Turner what he believes happened to Slater, Pisa added that the mobile phone's ping location could only be possible "if the phone was thrown" into the terrain.

He continued: "We're not obviously being kept up to speed, but he did tell me that he thought where the pin came from was rather surprising because it was really steep to get to, and it was covered in undergrowth and cacti.

"He said to get there you'd have to need a machete. Or he suggested, someone had thrown the phone into that growth."

In regards to the search that was abandoned, Pisa revealed that although the police search of the mountainous terrain has been called off, there are expert climbers who are "still searching with the backing of Jay's family".

He told GB News: "He's a dedicated hiker and mountaineer. He's saying he's also self-funding, and he's insisted he doesn't want anything at all from the family.

"I must admit, I've seen him up there several times, and he seems to be the more serious. He has experience in climbing in Scotland and various other places all all over the world. So he is still out there. He still has the backing of the family, but other than that, there is no active searching up there."
