The family of a man who was found dead in Spain say they are "absolutely heartbroken".
Tributes have been flooding in for the 34-year-old who moved to the Spanish city five months ago and was due to return this month.
The road worker's immediate family started to become concerned when they failed to hear from him and contacted the British Embassy in Spain.
Concerns for his welfare grew as days had passed without contact, which his family say was unusual for him.
His father Nick Fullagar and close friend Beth flew out to Spain last week to search for him.
The pair met with the Spanish police and broke into the apartment, discovering his lifeless body in his bed.
The cause of his death is not yet known.
Daniel's sister Kirsty Fullagar, 30, who says the pair were so close they were almost like twins, has paid tribute to her older brother.
"We spoke everyday, he was my rock," the mum-of-one said.
"It took almost eight days to find him.
"On day one I had got the worst feeling ever. I was sending him messages on Facebook but he was already dead.
"He was so energetic and full of life. He would always help anyone - he would be there in a flash.
"I would describe him like Tigger, he was the original nutter.
"My best memory is our holiday on a barge boat. My dad took us on it for a week, I was about 16 at the time.
"The Daniel song by Elton John will always remind me of him.
"It's our family song, my dad named him after it.
"I miss him so much and I feel absolutely heartbroken."
A GoFundMe page has since been launched, which has already raised more than £4,000 of its £6,000 target.
The money will be used to help fly Daniel's body back to the UK and give him the "send-off he deserves".
"I know people loved him, but I didn't realise the extent," Miss Fullager added.
"Tasha, who is a close friend of Daniel's, set up the fundraising page.
"I can't repay her enough. She spoke to the embassy and helped us find him.
"People have restored my faith in humanity - everyone has pulled together.
"Life's too short, it really is."
