The father of teenage girl killed as a passenger in a quad bike crash in 2012 is outraged at the sentence given on Thursday to a serial driving offender, less than a year after his release from custody after a separate incident of dangerous driving causing bodily harm.

Joshua Bonjour, 30, was sentenced to four years jail for the fatal crash in 2012 that saw 18-year-old Jodie Maree Worthington killed.

Only months after his release, Bonjour caused a crash that seriously injured his passenger, 25-year-old Lily Davis.

After completing a jail term for that offence, his licence was suspended but Bonjour was secretly recorded by police driving on 17 separate occasions over four months last year, for which he was sentenced to 12 months in jail on Thursday, but will be eligible for parole after serving six months.

Jodie’s dad Jeff Worthington (above) told Liam Bartlett on 6PR Mornings on Friday the justice system had let down his family, and so many others left to deal with similar tragedies.

“We’re just dumbfounded with the decision… I just can’t get my head around it,” he told Bartlett on Friday.

“It’s unbelievable… he smiled at me in court a fair few times, his father smiled at me in court a fair few times… he’s just the sort of person who doesn’t deserve to be in the public, because he doesn’t care about the public.

“If he crashes a car and kills someone, he’ll walk away. When he killed my daughter, he walked past my daughter who was on the ground dying and he didn’t even look at her… he picked up his quad bike and left her.”
