The defendant, Kristopher Rothery, was charged with aggravated assault, criminal negligence, and failing to provide the necessaries of life to his seven-week-old son, Jackson.
Jackson suffered severe injuries including subdural haemorrhages, rib fractures, and brain injury.
The court found that the injuries were inflicted by Rothery, who had shaken the child and subsequently failed to seek timely medical help.
Rothery's defence, claiming accidental injury during resuscitation and an honest but mistaken belief that the child was fine, was rejected.
The court found Rothery guilty of aggravated assault and criminal negligence, staying the charge of failing to provide necessaries of life under the Kienapple principle.
