The heartbroken grandmother of a toddler who died of massive head injuries after her drug-addicted mother and violent partner forced her to ride a motorbike that repeatedly crashed has wept with relief at a coroner's findings. Little Chloe Valentine, 4, died of massive head injuries after being forced to ride a motorbike that repeatedly crashed over a three-day period in the backyard of her Adelaide home in January 2012. Her mother, Ashlee Polkinghorne, and her then partner are in jail after pleading guilty to Chloe's manslaughter through criminal neglect. In an emotional statement outside the Adelaide inquest on Thursday, Chloe's grandmother Belinda Valentine welcomed Coroner Mark Johns' ruling that Families SA was broken and fundamentally flawed and that the agency's lack of action over Chloe's mother's drug use was a complete failure. 'The sun comes up tomorrow even though you don't want it to,' Mrs Valentine said. At an inquest into her death on Tuesday authorities said social workers missed the chance to save Chloe Valentine, 4, who died of massive head injuries in 2012 . In an emotional statement outside the Adelaide inquest on Thursday, Chloe's grandmother Belinda Valentine welcomed Coroner Mark Johns' ruling that Families SA was broken and fundamentally flawed . The inquest has heard Chloe was forced to endure chronic neglect at the hands of her drug-using teenage mother Ashlee Polkinghorne (left) and her partner Benjamin Robert McPartland (right) 'We are actually the lucky ones, because we had Chloe in our life', her grandmother said . 'We are actually the lucky ones, because we had Chloe in our life. 'She loved us, and we loved her very much. 'She will always be our four-year-old, but as we move forward she will always come with us. In a scathing verdict, the coroner found social workers 'flagrantly disregarded' their legal responsibilities to seize children from neglectful parents. Mr Johns said nothing short of a 'massive overhaul' was required by the agency. '(Families SA) took the path of least resistance, and the whole history of its dealing with Ashlee is a history of drift, irresolution and aimlessness,' he said. Mr Johns described Polkinghorne as an 'accomplished and manipulative liar' who easily fooled her case workers. 'Ashlee was given virtually limitless opportunities to address her problems,' he said. She was often given the benefit of the doubt by social workers, who helped clean her house and avoided confronting her about her drug use. Polkinghorne was also provided with three supported accommodation sites and government-subsidised childcare. The young girl was forced to ride a motorbike for days on end by her drug addicted mother and her partner . Chloe died in 2012 from head injuries sustained after being forced to ride a motorbike three times her weight for days on end by her drug addicted mother Ashley Polkinghorne and her partner at the time . Belinda Valentine said she repeatedly begged authorities to take Chloe off her parents and into her care . He said the agency made a 'mistake' when they declared it was unnecessary to drug test Polkinghorne, a known amphetamine user, and condemned the 'rigid' agency's failure to consider Chloe's grandmother as a potential guardian. Before Chloe died, Families SA received 20 abuse notifications from friends and family concerned about the girl's filthy, transient and unsafe living conditions. Handing down 22 recommendations to improve the system, Mr Johns said there had been a lack of analysis, lack of clinical supervision and a lack of leadership. During the inquest, counsel for Families SA, Michael Grant, said it wasn't clear whether Chloe would have been saved if the agency had intervened more forcefully. 'Families SA does operate in a hideous and imperfect world,' he said. 'It's not certain, in my submission, what would have happened if that circuit breaker had been applied.' The South Australian government is expected to respond to the coroner's finding later on Thursday. Mrs Valentine said the coroner's recommendations 'can be taken now'. Belinda Valentine (left) has slammed Families SA  saying they could have saved her granddaughter Chloe Valentine's (right) life . Ms Valentine said she called social worker Leanne Stewart from the scene of a domestic dispute pleading to take Chloe away from Ashley . However Ms Stewart (pictured) denied in court that such a phone call ever took place . A comprehensive review of Chloe's case had made clear that a 'circuit-breaker' was needed to save the girl from the chaos in her life . The coroner has asked why Chloe's mother Ashley was repeatedly given the benefit of the doubt . Families SA received 20 child abuse notifications during Chloe's short life from witnesses concerned about the girl's filthy, transient and unsafe living conditions .
