The boat was driven by the victim's father with the owner of the boat, cousin of the operator, sitting in the passenger seat.  They were pulling an inner tube with a 14 year old boy on one side, an 8 year old boy in the center and a 15 year old girl on the other side.  All were siblings.  The boat was travelling at approximately 20 mph and making turns causing the tube to cross the wake.  This activity had been going on for about 15 minutes with a couple stops before the accident.  Shortly before the accident, they met another boat that passed on the starboard side approximately 100 yards away.  I believe the inner tube crossed the wake of the towing boat then hit an incoming wave from the passing boat causing the 8 year old boy and the 15 year old girl to fall off.  The boy was not hurt.
