RedactedNarrative: Operator1 was operating vessel 1 with his 6 year old son right next to him. Vessel 2 was being operated by Operator2.   As they were cruising upstream, Vessel 1 suddenly turned right and ejected both occupants out of the boat.  After they were ejected, the unmanned boat circled back towards both individuals.  Operator1 pushed his son under water and dove under himself to miss the propeller.  The boat circled back and came towards them when Subject2 took over vessel 2 and intervened.  Vessel 2 was a brand new 2015 pontoon boat valued at $52,000.  Subject2 used vessel 2 and sheltered the two boaters ejected from being struck by vessel 1.  The unmanned boat circled and violently struck the pontoon boat three times before both of the Operator1''s were pulled from the Illinois River.  The unmanned boat quit operating shortly after.  The unmanned boat was recovered with the families Labrador retriever.  The Labrador showed no apparent signs of injuries.  Operator1 was transported to his boat where it started up and was driven back to the Starved Rock Marina
  
  An inspection of vessel 1 showed that there was a cut off switch, but no lanyard.  Operator1 was cited for operating a motor boat without a lanyard.  He was issued a written warning for a registration violation and no battery covers.  Vessel 1 was a custom 14 foot John boat had no capacity plate or motor size restriction displayed.  Vessel 1 had an oversized motor of 150 horse power motor on the back.
