Police are probing all possible sightings of Jay Slater as the hunt for the missing British teenager goes into its seventh day after his night at a Tenerife nightclub.
Now MailOnline has put together a timeline and map as the search goes on for the apprentice bricklayer, 19, whose disappearance has baffled investigators.
Spanish police have come under fire from Jay's friends - especially after rejecting an offer of help from Lancashire Police, who cover his hometown of Oswaldtwistle.
Officers using a helicopter, sniffer dogs, a drone and 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 - where he was seen dancing shirtless at a high energy music rave at Papagayo nightclub.
Here MailOnline highlights what is known since he went missing last Monday...

SUNDAY, 8PM
Jay had been attending a three-days NRG festival due to end last Sunday with events at the Papagayo Beach Club in South Tenerife.
Ahead of going back to the club, Jay sent his relative Isabelle Price a brief Snapchat video showing him and his surroundings in Arona, near the main party drag.

SUNDAY, 1AM
Pictures showed him walking through a sea of clubbers with sunglasses propped on his head at the festival where he was last seen by his friends on the Spanish island on Sunday night - while a photo showed him with friend Lucy Mae Law there.
New TikTok footage was shared online today showing him dancing shirtless in the nightclub - with the time said to be 1am as Sunday became Monday.
The after-party being held at the nightclub is known to have finally wrapped up at 5am - though it remains unclear at what precise time Jay left the venue.

He is thought to have headed to the £250-per-night AirBNB with two British men.

MONDAY, 8AM
His friend Lucy - who has since led criticism of Spanish police - received a phone call from Jay at about 8am, telling her he was 'lost in the mountains with no water' and just one per cent battery on his mobile.
The phone's last signal close to the Masca gorge beauty spot.
The walk from Jay's last known location to his accommodation would have taken about 11 hours on foot.
Lucy, who attended the NRG music festival with Jay, has since accused local police of 'not doing a good job' in the rescue efforts which have followed.

MONDAY, 8.15AM
This was the last - so far - confirmed sighting, with the Airbnb's owner Ophelia Medina Hernandez describing how she saw him walking at pace in the nearby village Masca - apparently heading away from Playa de las Americas.
Ophelia, the last person to see Jay, shared that Jay has also asked about catching the bus from the area before making the journey on foot - which was the only route
MONDAY, 8.50AM
Mr Slater’s phone died at about 8.50am, with his last known location registered to the Rural de Teno park near Masca where he had apparently stayed that night.
His father Warren, 58, and brother Zak, 24, have since travelled to a remote gorge above the village of Masca, 19 miles from the party resort of Playa de les Americas at an altitude of 3000ft to where Jay's mobile phone last pinged on Monday morning.
They looked on as mountain rescue teams and civil protection units with high-powered binoculars scanned the cactus strewn ravine looking for clues.
Choking back tears, Warren, wearing a bucket hat, sunglasses and black T-shirt, said: 'He's my son. I just want him back.'

Jay is reported missing by friends including Lucy, before the UK Foreign Office is alerted later that day. Police launch mountain rescue, then Jay’s mother and brother fly to Tenerife the following day after being informed on Tuesday morning.
Rescue teams have been scouring mountain areas with drones also surveying the scene
MONDAY, 6PM
A new potential sighting has now been reported by a man who says someone resembling Jay was sitting on a bench beside a church at Santiago de Teide, back closer towards Playa de las Americas.
Speaking to MailOnline, Jay's mother Debbie Duncan, 55, revealed that there has been a new sighting. She said: 'Someone has come forward to say they saw someone who they thought was Jay walking back down the road sat on a bench.
'He was with two men looking a bit worse for wear, and they were by a church, this guy has come forward and told the police about it and they are looking into it. We don't know if it was Jay for sure, but it's a start.
'They said it was about 6pm which is ten hours after he was seen by the lady in the village. But if it was him what was he doing there and who are these two men?
'All I know is that I am going to stay here for as long as it takes, I'm not going home unless it's with Jay. I'm not going anywhere until they find him.'
The sighting has not yet been officially confirmed.
