Daniel Liddell: Jet-ski rider tells court he is 'immeasurably sorry' after killing a young boy

A jet-ski rider who hit and killed a 14-year-old boy on South Australia's Murray River has faced court today, apologising to the boy's family for his irreversible actions. Teenager Cooper Henke tragically died in December last year when Liddell, who was doing donuts on a jet-ski, spun into the boys kayak. Another child was left seriously injured. Liddell recorded a blood alcohol reading of .08 after the crash, as well as reports of methamphetamines in his system.
