Family struggles to explain 'mum not coming home'

COAST mum Demmi Barr's car crash death has left her family struggling to explain to her young son why his mum is not coming home.

Miss Barr died in a Brisbane hospital on Thursday last week, after being critically injured in a car crash about 11.15pm on August 22 at Underwood, south of Brisbane.

Police said the 26-year-old man who was driving the car she was travelling in sustained leg and ankle injuries.

A 53-year-old man who was travelling in the other vehicle involved suffered non life-threatening injuries.

Miss Barr's mother Suzette Barr was there with a small group of close family and friends when her 22-year-old daughter's life support machine was switched off.

She had been there since rushing down the morning after the crash.

"I spoke with her like she could hear me," Ms Barr said.

"I put head phones on her and played her music."

But her daughter did not wake up.

"I stayed there for two nights.

"I didn't leave until she left."

Ms Barr said her grief had been eased by swapping stories about her daughter with her friends in the days since the crash.

"We just had a good laugh because she (Demmi) had the best sense of humour.

"I was lucky I had great support around me."

She said her daughter had a strong will.

"Demmi was a girl of attitude.

"What Demmi wanted to do, she did.

"We always loved each other.

"She always knew I was there for her."

Miss Barr had two younger sisters, Cheyenne and Ebony, as well as a four-year-old son.

"That's been the hardest thing," Ms Barr said.

"Trying to explain to him.

"We speak to a star in the sky at night and (say) 'mummy's asleep' and she is an angel looking after him."

She said Miss Barr absolutely loved her son.

"Her son was her life."

Family and friends are welcome to say their farewells at Gregson and Weight's Caloundra chapel from 9am Friday.

Ms Barr encouraged people to wear some white if they wanted because her daughter had a white ribbon in her hair when she first saw her in hospital.

She said her daughter's favourite colours were pink and purple.

Friends and family are also welcome to join Ms Barr for the scattering of her daughter's ashes at La Balsa Park at Point Cartwright on Saturday at 3.09pm.

Police are investigating the cause of the fatal crash.

A close friend of Ms Barr has set up an online fundraising page to help with money to support her family.
