Coroner: Agencies 'failed to protect' baby boy murdered by meth-addicted dad

CJ White was just 10-months-old when he was murdered by his meth-addicted father 鈥 a tragedy a Coroner says could have been prevented if police and Oranga Tamariki had acted on desperate warnings from his terrified family. 

In a damning finding, Coroner Mary-Anne Borrowdale said a 鈥渟uite鈥 of agency failures exposed systemic shortcomings, with authorities dismissing repeated pleas and an 鈥渙verwhelming fear鈥 the baby was in danger. 

Senior journalist Anna Leask reports. 

CJ died on July 10, 2019 from unsurvivable head injuries inflicted the previous day by his father, David Grant Sinclair. 

Sinclair denied intentionally hurting CJ. 

The court also heard that alongside 鈥渧ery severe brain and skull injuries鈥, there was 鈥渆xtensive bruising鈥 over CJ鈥檚 body and a broken bone in his foot. 

At least some of these injuries predated the traumatic brain injuries. 

Sinclair was sentenced to life in prison with a minimum non-parole period of 17 years. 

鈥淲hat happened to CJ needs to be heard and understood, especially by those who are empowered to address the kinds of acknowledged shortcomings that played a part in CJ鈥檚 death,鈥 said Coroner Mary-Anne Borrowdale. 

鈥淏aby CJ was a happy and healthy infant who was much loved by his mother and his grandparents. In the weeks before his death, CJ鈥檚 mother Laura White had tried directly 鈥 and through various Government agencies 鈥 to have CJ returned to her care.

鈥淪he was deeply worried that CJ was unsafe in Mr Sinclair鈥檚 home. Her efforts were unsuccessful.鈥 

Coroner Borrowdale said Oranga Tamariki had 鈥減roperly 鈥榓cknowledged and accepted鈥 a suite of failings in its response to CJ鈥檚 situation鈥. 

鈥淥ranga Tamariki failed to 鈥榗onnect the dots鈥 and to probe sufficiently to gain a proper appreciation of the risk that CJ was in,鈥 she said. 

She also criticised police who admitted 鈥渟hortcomings鈥 by officers dealing with CJ鈥檚 family and a 鈥渂reakdown in inter-agency collaboration鈥. 

鈥淐ertainly, aside from some very limited information-sharing over the telephone, there was no meaningful collaboration between police and Oranga Tamariki to protect CJ,鈥 she said. 

鈥淟aura was bounced from agency to agency as she - increasingly desperately 鈥 tried to ensure that someone would act in CJ鈥檚 interests by removing him from his father鈥檚 home. 

鈥淏oth agencies let Laura and CJ down.鈥

CJ was born on September 6, 2018. His parents were not in a relationship and both had other children. 

White, who had faced her own struggles, returned to Hokitika to be near her supportive parents before CJ鈥檚 birth. 

Before his death, CJ was 鈥渄oing well鈥. He was a happy, healthy and 鈥渄elightful鈥 baby who was learning to crawl and saying his first words. 

His maternal grandparents formed a strong bond with CJ and said White was 鈥渁 good mother鈥 and they had no concerns about her parenting. 

The coroner鈥檚 report outlines a difficult relationship between White and Sinclair. 

He was said to be 鈥渁ngry鈥 when he found out White was pregnant with CJ and 鈥減unched the wall鈥. 

After CJ鈥檚 birth, 鈥渢ension grew鈥 between the pair around who would care for him. 

Sinclair wanted to increase time with CJ, despite White鈥檚 concerns about his drug use and associates. 

After a number of tense months, White agreed CJ could be left alone with his father. She went and stayed with Sinclair at his home for a period to 鈥渟ee and confirm鈥 that the man 鈥渨as capable of properly caring for鈥 the baby. 

鈥淟aura stayed a few nights and satisfied herself that Mr Sinclair had the skills and equipment to care for CJ. However, she also says that during the stay she saw Mr Sinclair using drugs,鈥 said the Coroner. 

鈥淟aura says that she did not plan to leave CJ for more than a week, and that she had immediate misgivings about the arrangement as soon as she left Mr Sinclair鈥檚 house.鈥 

White had to travel to Blenheim for her other children and stayed for 12 days. She said Sinclair messaged her regularly to report on 鈥渉ow well CJ was doing鈥 with him. 

While she was away, White鈥檚 father contacted Plunket to report concerns that Sinclair had sole custody of the baby, 鈥渘otwithstanding that he was rumoured to be involved in drug-taking鈥. 

Plunket relayed this information to Oranga Tamariki and staff 鈥渟poke of organising a visit to assess how CJ was doing鈥.

When White returned to Hokitika, she went to pick CJ up. 

She told the coroner that Sinclair had 鈥渓ooked like he had been smoking meth鈥 and refused to wake the baby and asked White to leave. 

The next day she asked to see CJ and Sinclair refused, saying he had applied for custody and would be in touch once it was sorted. 

鈥淚n regards to seeing him in mean time, he ain鈥檛 going anywhere with anyone or leaving my sight again,鈥 Sinclair told White in a message. 

She did not have any further direct contact with him. 

鈥淟aura tried to enlist WINZ, Oranga Tamariki, the police, a lawyer, and the Family Court in her efforts鈥 to regain custody of CJ. 

鈥淏y the time CJ died, these efforts had not succeeded. In tragic timing, on 10 July 2019 鈥 the day that CJ died 鈥 Laura鈥檚 lawyer advised application to the Family Court for a parenting order had been declined.鈥 

The coroner鈥檚 report contains harrowing details of CJ鈥檚 death. 

A post-mortem investigation found dozens of bruises, a large skull fracture and catastrophic brain injuries consistent with high-speed crash trauma. 

Coroner Borrowdale explained the purpose of her inquiry was to establish 鈥渨hether anything could have been done to prevent CJ鈥檚 death鈥. 

鈥淚f there are lessons to be learned from this tragedy, we need to learn them and do our best to ensure that such a thing never happens again,鈥 she said. 

鈥淚n this case, this has really amounted to asking whether CJ could and should have been removed from his father鈥檚 house.鈥 

She said it may be self-evident that the baby 鈥渨ould not have been in harm鈥檚 way if Laura had not left him with his father鈥, it was important to remember that she 鈥渃ould not then foresee that Mr Sinclair would refuse to return CJ to her or what he would do to him鈥. 

鈥淎nd 鈥 especially relevant to my inquiry 鈥 Laura tried very hard to get CJ back. 

鈥淟aura was aware that Mr Sinclair used methamphetamine and believed him to be dealing drugs from home. Laura was right,鈥 the coroner said. 

鈥淪he told her family this. She told Plunket; Family Start; Oranga Tamariki; the police; her lawyer; and the Family Court. 

鈥淒id any of those social and government agencies have a basis to remove CJ from his father鈥檚 home? Did they do all that could reasonably be expected of them to look after CJ鈥檚 interests? My views on those questions follow.鈥 

The coroner said White and her family had some awareness of Sinclair鈥檚 use of 鈥渉ard drugs鈥 and 鈥淐J鈥檚 maternal grandfather, described himself as having 鈥榓n overwhelming fear that CJ was going to die鈥,鈥 she said. 

Coroner Borrowdale made lengthy findings about each agency involved in CJ鈥檚 case. 

She was satisfied that Plunket 鈥渁cted appropriately, and followed correct processes鈥 and reported concerns properly to Oranga Tamariki. 

鈥淚 am not persuaded that Plunket could have done more at that time, and Oranga Tamariki was the right agency to take forward the allegations of risk to CJ,鈥 she said. 

Coroner Borrowdale said aspects of OT鈥檚 response 鈥漺ere specifically inadequate鈥 - particularly when White and her parents 鈥渞epeatedly voiced desperate concerns that CJ was at risk鈥. 

She said it was 鈥渟obering鈥 to have White鈥檚 father tell her 鈥淚 don鈥檛 think we pushed鈥 hard enough with Oranga Tamariki鈥.

鈥淭hey pushed as hard as they knew how. But in practice, the proper child protection response should not depend on the agency being repeatedly urged to act,鈥 the coroner said. 

鈥淔amily had met their duty by registering their concerns with Oranga Tamariki, and it was then for the agency to act. 

鈥淭here was then no attempted uplift of CJ. The inexperienced, under-supervised and incompletely trained junior social workers, who considered the reports of concern about CJ, did not consider him at risk, so they took no steps to alter his living situation. 

鈥淥f course, Oranga Tamariki needs to consider questions of plausibility and proportionality when deciding its response, but staff ought to be encouraged to listen to the information and instincts of wh膩nau, friends, neighbours and community members who come to it and report grave concerns for a child. 

鈥淚t is no small matter to screw up the courage to approach Oranga Tamariki, and it behoves the agency to take such reports extremely seriously.鈥 

Coroner Borrowdale further slammed OT for the way staff treated White. 

鈥淚 am troubled by the wariness that staff displayed in dealing with Laura鈥檚 concerns. Its records focus largely on Laura鈥檚 mental state, her housing situation, and her personal history,鈥 she said. 

鈥淚t was relevant for the social worker to ask Laura, 鈥榳hy she had left CJ with his father who she knew to be doing drugs?鈥 But to my mind, the question is redolent of a 鈥榶ou made your bed, now lie in it鈥 approach. 

鈥淚t appears that Oranga Tamariki鈥檚 wariness of Laura infected its response.鈥 

Coroner Borrowdale listed a number of other 鈥渟ignificant shortcomings鈥 in OT鈥檚 response to White and investigations of CJ鈥檚 safety and his father鈥檚 drug use. 

She was also critical of CJ鈥檚 case being assigned to staff who were 鈥渏unior and ill-equipped鈥.

鈥淥ranga Tamariki failed to 鈥榗onnect the dots鈥 and to probe sufficiently to gain a proper appreciation of the risk that CJ was in,鈥 said Coroner Borrowdale. 

鈥淭he agency accepts that and has made some changes. Its continued under-staffing in the West Coast area, however, leaves me unpersuaded that the resourcing constraints that led to the mishandling of CJ鈥檚 case are not a continued problem, and concerned that they may yet resurface in future child protection cases. 

鈥淧olice have properly acknowledged shortcomings in responding to the concerns for CJ expressed. The police retrospective review rightly found that Laura鈥檚 concerns should have been treated urgently and escalated. 

鈥淢r White also felt that he was not taken seriously on the two occasions, during a single day, when he entered the Hokitika station to report his worries for CJ. He was left in tears by the response of police. 

鈥淭his is powerful evidence of the extreme helplessness he felt in trying to protect a child that he and his wife desperately loved. Mr White鈥檚 concerns 鈥 like his daughter鈥檚 - should have been handled with the utmost seriousness and sensitivity.鈥 

Coroner Borrowdale said in the year leading up to CJ鈥檚 death, nine social and government agencies were involved with White and her children. 

鈥淕iven the history of agency failure to protect CJ, it is striking to read,鈥 she said. 

鈥淧olice have acknowledged that they were 鈥榙isconnected鈥 from Oranga Tamariki in this place, at this time, and have provided assurances of much stronger collaboration 鈥 supported by better, clearer processes 鈥 today. 

鈥淏oth Oranga Tamariki and the Police have accepted making errors when apprised of the risks that Mr Sinclair posed to CJ. 

鈥淥ranga Tamariki found and acknowledged numerous faults鈥 The review findings were succinctly captured as: Oranga Tamariki had an opportunity to intervene earlier. In summary, Oranga Tamariki accepted that its social workers had essentially dismissed the concerns of the maternal family. 

鈥淏oth agencies let Laura and CJ down. I encourage police and Oranga Tamariki to commit heavily to making their current joint investigative approach a success.鈥 

Coroner Borrowdale said in the time that has passed since CJ鈥檚 murder both OT and the police had made significant changes to their processes. 

鈥淲e accept the coroner鈥檚 findings and acknowledge that aspects of our practice and involvement with CJ鈥檚 family fell short of the standard we would expect,鈥 said OT chief social worker and deputy chief executive of professional practice, Nicolette Dickson.

Dickson said analysis of CJ鈥檚 case for the coroner 鈥渇ound gaps鈥 in the agency鈥檚 handling of the concerns raised about him. 

鈥淭hat led to missed opportunities to intervene,鈥 she said. 

鈥淲e made changes to address these practice concerns.鈥 

Tasman district commander Superintendent Tracey Thompson said police also accepted the coroner鈥檚 criticism. 

鈥淲e accept that there were shortcomings by the New Zealand police, and, on behalf of the police, I do want to apologise to CJ and to CJ鈥檚 family and provide my sincerest condolences to them,鈥 she told the Herald. 

鈥淪ince this tragic incident, we have worked to identify what the gaps were, what were the opportunities that were missed - and to work towards this never happening again.鈥 

Thompson said concerns raised about CJ should have been noted as a family harm issue immediately. 

Had that been done, the concerns would have been 鈥渞eviewed straight away鈥. 

鈥淥ur family harm team would have looked at it, assessed it, and actioned what needed to be done, within a timely manner,鈥 she said. 

鈥淲e鈥檝e been really committed and focused on ensuring that our staff - particularly those that are at the front counter and are the first points of call to people that come to the station - (have) training on understanding what constitutes family harm matters, that they鈥檝e got information that we need to risk assess, analyse, and act on accordingly. 

鈥淧eople come to us because they need assistance and they want help, and we need to make sure that we provide that to them.鈥 

A spokesperson for Minister for Children and the Prevention of Family Violence Karen Chhour said 鈥渕y office won鈥檛 be commenting鈥 when asked about CJ鈥檚 case. 

Police Minister Mark Mitchell鈥檚 office did not respond.
