THE mother of a young Redlands woman killed by a drink driver in 2009 has launched a petition for harsher penalties for youth criminals, attracting more than 85,000 signatures in a day.
Judy Lindsay's 20-year-old daughter Hayley Russell was killed in a car crash at Alexandra Hills in 2009.
Ms Lindsay started the online petition after the deaths of young Alexandra Hills couple Matthew Field and Kate Leadbetter on Tuesday.
The pair were crossing Finucane Road at the pedestrian lights while walking their dog when they were struck by a four-wheel-drive which police allege had been stolen from a Cleveland property earlier in the afternoon.
A Waterford West teenager has been charged with two counts of murder.
Ms Lindsay called for the Youth Justice Act to be reformed to give harsher sentences for re-offending juveniles.
"We will never see our loved ones that have lost their lives ... on our roads," she said.
"We will never have grandchildren and never see them again."
One supporter said there should be no more slaps on the wrist for young offenders.
Another said repeat offenders should be penalised to the full extent of the law.
Speaking on Sunrise this morning, Premier Annastacia Palaszczuk said the crash was a tragedy.
"There will be a coronial investigation," she said.
She told Nine's Today program she was open to tightening bail laws.
"If there's anything more that we can do to strengthen our laws we absolutely will, but at the middle of last year, we actually tightened the laws significantly. We said that there is a presumption against bail," she said.
At a candlelight vigil for the pair on Wednesday, Ms Leadbetter's aunt Danielle said laws should be rewritten to ensure that people convicted of crimes were made to serve their time.
"We don't want this to happen to other people," she said.
On Wednesday, Assistant Commissioner Brian Codd urged people with information or CCTV footage to come forward.
"I appeal for people to recognise that even the smallest piece of information could be vital in us building the case," he said.
Between the beginning of the year and January 24, 15 people died on Queensland roads.
