Felix Hua who disappeared in May 2009 during a field trip.
A carer who was unqualified to look after a severely autistic boy who drowned during a field trip should not be blamed for the teenager's death, a coroner has ruled.
On Thursday Coroner Heather Spooner ruled that Vipula Rajakaruna Mudiyanselage lacked the knowledge to care expertly for Felix Hua because he was not aware of the boy's disabilities and lacked the training and support from his then employer, Southern Cross Care.
Mr Rajakaruna Mudiyanselage was caring for Felix in his role as a community support worker when the 14-year-old went missing at Yarra Bend Park in Fairfield on May 30, 2009.
Felix's body was found three days later in the Yarra River, near Dights Falls, after an extensive search by police and the SES.
