‘Way too young and beautiful to leave this earth way too soon, bless her and her family. Breaks my heart,’ one person wrote.

‘So sorry to hear you lost your daughter. Losing a child is very painful. Cherish the memories, fly high sweet angel,’ another said.

Ms Dean’s friend, Amy Todd, shared a series of photos alongside a message the day after the 21-year-old died.

‘Since we first met as kids we knew we were soul bound, even years apart could never break us,’ Ms Todd wrote.

‘Today I feel like I have lost a part of my soul. I will miss you everyday, think about you every night.

‘I love you Caitlyn, you saved my life. Fly high and return to wonderland.’

So far this year 25 people have lost their lives on southeast Queensland roads with a total of 163 deaths across the state.

Ms Dean was part of the Coastal Junior Roller Derby where she competed under the name ‘Tainted Halo’ and number 6666.

It’s the second tragedy the association has suffered in the a little over a month.

Ms Dean’s teammate Keira Dascoli-Guymer, from Nambour, collapsed on June 17.

The 18-year-old was rushed to the Sunshine Coast University Hospital‘s intensive care unit where she spent 10 days in a coma.

Her family on June 27 made the heartbreaking decision to switch off her life support.

At the time, Ms Dascoli-Guymer’s said she was fit and healthy and doctors were unable to determine what caused the sudden episode.

‘She didn’t have a heart attack … her heart just stopped and they don’t know why,’ her mother, Lisa Guymer, told the Courier Mail.

‘It’s hard to try and accept they don’t know, and we may never know.’

Mrs Guymer described her daughter as a roller derby fanatic.
