JAY Slater's dad has spoken of the family's anguish amid growing fears others are involved in the missing teen's disappearance - and insists: "Everything stinks".
Desperate Warren, 58, returned to the mountainous region in Tenerife where the 19-year-old vanished on June 17 to resume the search in the hope of finding a breakthrough.
But as questions grow around Jay's last night before he vanished, Warren said: "Everything stinks.
"It’s just a riddle and I don’t know the outcome."
Warren went on to say that he believes the two men who last saw Jay could be key to helping finally find him.
He added: "My starting position, I’ve said this from day one, ask the two men who’ve taken him - and then start from there."

He went on: "We’re going round and round in circles.
"If they want to go and search a house they have to go to court first."
Jay vanished after returning to a £40-a-night Airbnb with convicted drug dealer Ayub Qassim, 31, and another as yet unidentified male.
Both men have been ruled as "not relevant" by police - and Ayub has protested he has "nothing to hide".

Today, it was claimed by ex-cop Mark Williams-Thomas that Ayub goes by the name "Johnny Vegas".
The mysterious nickname had been swirling around the case for weeks - and it was originally assumed to be the second man.
Jay left after spending the night at the remote cottage in Masca and then telephoned friend Lucy Mae Law, 18, to say he was "lost in the middle of nowhere", with no water and only one per cent left on his phone battery.
Spanish police searched for 12 days but called it off last weekend with no trace of Jay.
His family are now leading fresh attempts to find him within the rugged terrain high up in the mountains overlooking the party island.
Warren added: "I was quite disappointed last Saturday when they did the search, they said the whole island was going to turn out.
"Let all the big boys do it, the police told me the big, big search was Saturday.
"We got down in that valley at 2pm and there wasn’t a soul.
"They might have been there I don’t know, they might have been there before me.
"But I was quite disappointed because I expected every fire engine, ambulance...to be looking for him.
"You need Columbo."
Mr Williams-Thomas - who has been working with the family - today posted a sensation video update on the case.
He claimed that his digging had Jay had come into contact with an "established criminal network" in Tenerife.
But he did not elaborate - and could not say whether or not think link had anything concrete to do with his disappearance.
He also revealed that "Johnny Vegas" was Jay's new pal Ayub.
Ayub provides details of Jay's trip back from the music festival to the Airbnb - in which he left after saying he wanted some food.
The bricklayer, Oswaldtwistle, Lancs, has been missing for almost three weeks after going missing in the early hours three weeks ago.
He was attending the NRG music festival in Tenerife on his first "lads holiday" - before leaving the night out with two men.
He returned with them to their Airbnb in the mountain village of Masca.
The following morning Jay is believed to have tried to get back to his accommodation in Los Cristianos.
But after a phone call with his friend Lucy Mae Law in which he is said to have revealed his battery was 1 per cent and he cut his leg on a cactus - he vanished.
The search has been the subject of intense interest - and many questions remain over what happened to Jay on his night out.
Both men have been ruled out of the investigation.
Other mysteries around the case focus Jay allegedly admitting he stole a "Rolex watch" worth £12,000 on the night he disappeared.
But the case has also sprung up countless conspiracy theories and become an obsession for online sleuths.
Hundreds of thousands of Facebook detectives has signed up to various chat groups as they pour over detail.
Cops used sniffer dogs, drones, a helicopter, dozens of volunteers and mountain rescue experts but to no avail .
They officially called off the search last Sunday.
And Jay's uncle Glen Duncan yesterday angrily hit out at the police investigation, saying he wished he could "burst into the police station" and saying he fears a "third party" could have been involved.
He told The Sun yesterday that he doesn't believe police are taking the search seriously and labelled it a "massive let down".
He said: "I don't know if they're following up every single lead. I feel like marching down there myself and bursting into the police station.
"What are they actually doing now, the police, I mean they're not searching with the helicopter are they?
"Are they doing door to door inquiries or sitting there looking at CCTV images?"
Jay's devastated uncle vowed: "We're still holding onto hope - we have to because we don't know.
"It's just torture every day. It's got to a point now where the sadness has gone and it's just anger."

He also drew a heartbreaking comparison to the case of missing girl Madeleine McCann, saying - like her family - they will never give up hope.
The family's GoFundMe set up to help fund the search for Jay has reached over £50,000.
The Mysterious Case of Jay Slater - 3 WEEKS ON
MONDAY July 8 marks three weeks since Jay Slater, a 19-year-old from Oswaldtwistle, Lancashire, vanished in Tenerife.
The apprentice bricklayer, who flew out to the popular holiday island for a rave festival with friends Lucy Law and Brad Page, has made headlines around the country.
On Sunday June 16 the three of them headed off to one of the events at Papagayo nightclub.
In the early hours of Monday 17 - Lucy and Brad were ready to head back to their hotel, but Jay wanted to keep partying.
It was then that he left the south of the island and headed to an Airbnb in the northwest with two British men.
The Sun revealed the identity of one of them - convicted drug dealer Ayub Qassim, who spent nine years behind bars in the UK.
For days it was thought that the second mystery man went by the name ‘Johnny Vegas’.
On Sunday former detective Mark Williams-Thomas, who is out in Tenerife investigating, said Qassim told him he is in fact the man behind the nickname ‘Johnny Vegas’.
We don’t yet know the identity of the second man - who remains a key part of the puzzle in Jay’s mysterious disappearance.
Qassim claims he drove Jay and the friend back to their accommodation and said they all went to sleep.
In the morning he offered to drive the teen back to the Los Cristianos resort after a nap, but Jay, hungry and tired, said he wanted to leave immediately.
Lucy, the last person to speak to Jay, claims she had a panicked call from him soon after he left the holiday let, telling her he was lost and thirsty, his phone was about to die and that he’d been cut by a cactus.
Jay had been seen by the owner of the Airbnb that morning wandering around near the Rural de Teno park - a mountainous region close-by.
He is believed to have been attempting the 11-hour trek back to his hotel, despite the alleged offer of a lift and more buses scheduled for the day.
It was there that his phone last pinged - and he hasn’t been seen or heard from since.
Mark Williams-Thomas has claimed he left the Airbnb quickly, and was “scared”.
Bizarrely, Qassim says he was woken up that morning by a phone call from an unnamed friend of Jay, saying he was “in a ditch” somewhere and had been “cut by a cactus”.
Jay’s friend Lucy claimed to have “tracked down” the two men in the Airbnb after he vanished - quizzing them on the morning of Jay’s disappearance.
Some reports have suggested Lucy knew the two men, although it is not clear how.
She has dubbed his disappearance “weird and suspicious”.
Both men were questioned by Spanish cops on June 17 but quickly deemed “irrelevant” to the investigation and cleared to fly back to the UK.
Police spent almost two weeks searching for Jay in the Tenerife mountains, scouring a 2,000ft ravine, before calling it off on Sunday June 30.
Jay’s family have repeatedly slammed the Spanish investigation into his bizarre disappearance.
His uncle, Glen Duncan, is convinced of “third party involvement”.
He told The Sun: "My starting position, I’ve said this from day one, ask the two men who’ve taken him - and then start from there."
A number of unanswered questions remain, over why Jay would have travelled so far with two older men he didn’t know, why said men would have taken him in, and why he braved the Tenerife mountains with no phone battery, water or heat protection for a day-long walk.
