Mystery still surrounds the disappearance of British teenager Jay Slater who vanished after leaving a rave after party five days ago on the holiday island of Tenerife.
Police using a helicopter, sniffer dogs and a drone, as well as mountain rescue units have been scouring countryside close to an AirBnB he went to with two British men.
The isolated farmhouse was an hour's drive from the popular hotspot of Playa des Los Americas in southern Tenerife, in the village of Masca, 19 miles away.
MailOnline has pieced together the last few hours before he disappeared and has tried to answer a series of puzzling questions that have left police and his family stumped.
The first and most troubling is just where has the apprentice bricklayer from Oswaldtwistle, Lancashire got to.
Jay Slater, 19, (pictured) was last heard from at 8.50am on Monday when he messaged his friend Lucy Mae Law to say he was lost and trying to make his way home

He arrived in Tenerife on June 12 with two friends – one named Brad and another Lucy Mae Law, who was the last person in contact with Jay before he vanished.
Timeline of Jay Slater's disappearance
June 12 - Jay arrived in Tenerife last Wednesday with his friend for the NRG rave a three day festival from 14-16 June at Los Cristianos.
June 17 - In the early hours of Monday morning Jay is pictured at the after party at Xanadu enjoying himself with pals including Lucy Mae West.
2am - Lucy decides to leave and head back to her apartment but Jay remains at the party and gets chatting to two British men he has met.
5am - Jay and the two men leave and make an hour car journey along the tortuously twisty mountain road to the Air B and B at Masca where the two mystery British men are staying.
6am - Neighbours at Casa Abuela Tina report noises from the house.
7:30am - Jay sends a picture of the view from Casa Abuela Tina and a picture of him holding a cigarette on the stone doorstep of the house.
Around 8am - Jay is seen by a local woman and he asks her how to get back to Los Cristianos by bus. She tells him the next one is not until 10am.
8.15am - The same woman says she saw him walking up the mountain and the wrong way
8.50am - Jay calls Lucy to say he has one percent on his phone and he is lost and has no idea where he is and he is trying to walk back Los Cristianos.
A short while later his phone pings from a location close to the Mirador La Cruz De Hilda restaurant which overlooks a vast canyon and which is being searched by police.
The group had arrived for the NRG three-day festival that kicked off last Friday and ended with an afterparty into the early hours at Papagayo, on the notorious Playa des Los Americas strip.
Jay, Brad and Lucy joined hundreds of other party goers for the rave which was billed as a 'weekend of electrifying music, stunning visuals, and innovative productions.'
Video taken from the party shows Jay smiling and dancing and it was here that Lucy and Brad saw him for the last time, with both leaving at around 2am while he stayed on with two British men he had met.
It's known that at around 4am just as the party was wrapping up police were called to Veronica's Strip to deal with 'an incident' but there is no suggestion Jay was involved in what happened.
He is then known to have left with the two men at just before 5am and headed back to their rented AirBnB called Casa Abuele Tina, a journey along a twisting and turning mountain road.
Lucy told MailOnline Jay had told her he was going with them and she urged him to 'get back' to their room at the Paloma Beach hotel but he refused and insisted he was going off with them.
Lucy said:' I just don't understand why he went to their place, he'd only just met them and didn't know them at all. Brad and I said to come back but he didn't, if he had this wouldn't have happened.'
Just who were these two men ? Little is known about them but they were described by Lucy as 'black and British' and MailOnline has spoken to the owner of a bar next door to the property who said she heard people in the house at 6am.
While here at 7.30am Jay sent two Snapchat pictures to Lucy and his mother showing the view from the house onto the nearby valley and one of him holding a cigarette on the doorstep of the house.
Half an hour another witness traced by MailOnline, Ofelia Medina Hernandez, said she had seen Jay standing by the bus stop directly outside the AirBnB and had asked about buses back to Los Cristianos.
Ms Medina Hernandez explained that the next bus down the mountain in the Parque Rural de Teno was not until two hours later at 10am.
She said: 'I held up my fingers on my hands to say 10am as he didn't understand me then I went home briefly before driving up the mountain to Buenavista del Norte, but this time I saw him walking on the road out of the village.
'It was no more than ten or fifteen minutes after I had spoken to him and he was about a kilometre from the house. I drove past him and that's the last I saw him.'

Lucy told MailOnline that the last message she had from him was at 8.50am when he told her he was 'lost, needed water and had 1 per cent battery' on his mobile and that he was going to try and walk 11 hours back with no trace of him since.
But using the images he had sent her Lucy was able to track down the house where he had been staying with three hours after his last message and spoke to the men who were there.
She said:' They seemed startled and surprised that I had found them, and I asked them where Jay was.
'They said he had gone out to try and look for cigarettes and then come back and said he was leaving to try and get a bus back into town.
'They just seemed shocked that I had managed to find them and I know the police have spoken to them but I've since found out they have left the country. They need to be spoken to properly.'
Lucy added: 'What I don't understand is if he did walk down then why wasn't he seen by anyone? It's a busy time of day, the place is full of hikers and holidaymakers, he could have asked them for help or stopped somewhere but no one has seen him at all.'
The house – in the Parque Rural de Teno – was rented out by the two men from Friday to Monday but they stayed on a extra day after being questioned by police following Jay's disappearance.
Locals have told MailOnline one of the men is known as 'Johnny Vegas' and Spanish police confirmed they had the names and passport details of both and sources say they posted a Snapchat image of themselves back at Gatwick.
Frantic mother Debbie arrived on Tenerife on Tuesday after being woken by Lancashire police at home to tell her jay was missing and she should 'head out there' to try and help find him.
At 7am she flew from Manchester to Tenerife with son Zak and shortly after she arrived was sent a menacing message on Snapchat that read: 'Kiss goodbye to your boy, you're never going to see him again, he owes me a lot of money.'
Jay was reported missing on June 17 after he failed to return to the apartment he was sharing with friends in Tenerife, Spain following a night out and he has not been seen since

Debbie has passed the message to police and although she is convinced he is being held 'against his will' police say they are 'keeping an 'open mind' and have 'not ruled anything out or in'.
It's not known who sent Debbie these messages and it begs the question that Debbie is asking – was he kidnapped and is he being held to ransom? Did he walk the wrong way because he was trying to get away from someone ?
MailOnline has been told the last signal from Jay's phone was at the Mirador la Cruz de Hilda restaurant which has dramatic views over the Masca canyon and is criss crossed by trails that have nerve-jangling drops.
Friends of Jay's have trawled the area for hours and although daytime temperatures are not to excessive at around 27c at night the thermometer plummets to just above zero due to the high altitude.
MailOnline can also identify the owner of the AirBnB as former mayor of the nearby town of El Tanque, Roman Antonio Martin Canaves.
But all attempts to contact him have been met with silence, messages are not returned and calls unanswered although there is no suggestion he has done anything untoward although the property is now listed as 'unavailable'.
What is known about him is that in 2020 he was disqualified from public office for a year after being convicted of 'prevarication' in relation to the running of an elderly day care centre.
But for the moment thoughts go out for Debbie, who has been left frantic with worry as any mother would be and who told the MailOnline she 'just wants my little baby boy back' and who should have welcomed him home but instead is worried sick for him.
