“You really were the life of the party, we made so many memories us 4 and I couldn’t be more grateful to know you.
“Honestly sat here thinking of them is making me smile. This world is so so cruel and it’s really not fair. Rest in peace Gracie you will be so missed. Thinking of your family and friends.”
Brennan Newton posted: “She will be missed loads, heart of gold absolutely gutted X.”
By Sunday morning, a GoFundMe page set up to help Ms Spinks’ family by Abbey Griffin, one of her friends, had raised more than £5,800.
Ms Griffin said: “Gracie was a beautiful girl at just 23 years old she had already touched so many people’s life and what gorgeous memories she leaves behind.
“She was a caring and loving individual and was always happy to help. She was also so so stubborn and she’d always stand up for what was right.
“If you knew Gracie you’d also know she was horsey mad and had the most gorgeous horse called Paddy whom she loved dearly.
“Although no amount of money could ever bring Gracie back, I ask that you please donate what ever you can to help her family at this moment.
“We all love you so dearly Gracie, behave up there.”
Ms Griffin also said she would be organising a balloon release from the Markham Vale business park, where Ms Spinks worked, on Monday 28 June to allow her friends to say their goodbyes.
Ms Spinks had also been working as a part-time model, The Sun reported.
