Jay Slater's best friend Lucy Mae Law shares emotional tribute to the tragic teenager as she joins hundreds at his funeral

Among the 500 mourners at Jay Slater's funeral was his best friend Lucy Mae Law - the last person to speak to the teenager on the day he went missing in Tenerife.

While his family and closest friends read heartwarming eulogies and poetry inside, a sea of mourners dressed in blue - Jay's favourite colour - gathered outside the chapel to watch the funeral on a large screen.

It was here that Lucy Mae remembered her friend by holding a blue rose and posting a story to her Instagram which read: 'Rest in peace buddy. You will never be forgotten.'

The apprentice bricklayer, 19, went missing on the Spanish island of Tenerife on June 17 after attending the NRG music festival with several of his mates - including Lucy Mae.

She claims that Jay called her at around 8am on the Monday morning, telling her he was 'lost in the mountains, he wasn't aware of his surroundings, he desperately needed a drink and his phone was on one per cent'.

Before the call abruptly ended, Jay told Lucy Mae he was attempting the 11-hour walk back to his holiday accommodation at the Paloma Beach.

But he headed the wrong way baffling investigators and his family.

After an extensive month-long search, Jay's body was tragically found down a rocky ravine with traumatic head injuries consistent with a fall from height.

His short life was remembered today at a funeral service held at Accrington Crematorium Chapel in Lancashire today.

Jay's body arrived in a horse-drawn carriage in a blue coffin with 'JAY' embossed on the side.

His mother Debbie Duncan, 55, and father Warren Slater, 58, sobbed as they followed his coffin into the quaint church.

Instead of leaving flowers, Jay's loved ones asked for well-wishers to donate to LBT Global - the overseas crisis support charity who supported search efforts and helped his family through their heartache.

Videos of the young teenager playing football, which he started from the age of six, and of him dancing at festivals brought laughter to those inside the chapel.

In an eulogy, his friend James Curry said he was 'more than a mate' and 'more like a brother'.

Mr Curry, who was due to start a business with Jay, added: 'Jay was one of a kind. He lit up any room with that goofy smile of his.'

His close friend said he 'cherished' his time with him as poems were also read out during the service. Another said: 'Keep partying up there'.

Outside, people were seen carrying blue flowers, wearing blue wristbands and ribbons. Some even let off blue smoke bombs in Jay's memory.  

Jay's coffin was carried outside for burial to the sound of a drum-and-bass track - perhaps fittingly for Jay, a known raver.

After the service finished, Lucy Mae posted another heart wrenching tribute to Jay on her Instagram story - a picture of two blue roses and two cards addressed to the late teenager.

Although the message was blurred, the top of the card said 'In loving memory' and 'Night, night. Sleep tight.'

Lucy Mae has been posting a string of photographs and videos of her late friend in the lead up to his funeral.

Yesterday a short clip showed Jay, a carefree 19-year-old, bopping away at a pool rave. Lucy Mae wrote: 'Dancing as always'.

While the manhunt continued, Lucy Mae blasted local Spanish police for 'not doing a good enough job' in finding the missing Brit.

'We are having to do this all by ourselves as Spanish police are not doing a good enough job. They don't even speak English. It's been a very slow process here so we need the British police to come out and help them,' she told The Times.
