“I feel immense pain as if someone stabbed me in my heart,” the mother wrote in a victim impact statement read out in the District Court on Thursday.
The statements of the parents – who can’t be named – were read out by a support person at the sentence hearing of Chinese self-help practitioner Hong Chi Xiao.
A jury in October found the 56-year-old guilty of manslaughter for breaching the duty of care he owed the boy through gross negligence.
The boy’s last insulin injection to treat his type 1 diabetes came on the first day of a week-long “radical” Chinese slapping and stretching therapy workshop in April 2015.
His relatives said Xiao instructed them to stop the regular blood glucose tests and insulin injections.
He told them the boy’s increased vomiting showed toxins were leaving his body.
In his statement, the boy’s father said time would never heal the gaping wound in his heart over the loss of their beautiful son.
“He was becoming my best friend,” he wrote.
Xiao will be sentenced on Friday.
