RedactedNarrative: victim was on Cave Run Lake aboard a pontoon (KY 0577 JX) that her husband had rented from the Marina on July 13th, 2014.  Victim was on the 24ft Solid Craft pontoon that was located around the Twin Knobs Beach area of Cave Run.  According to her husband, the pontoon was stationary and his wife had just applied suntan lotion to her body and was attempting to climb the steps to gain access to the top in order to sunbathe.  According to Operator, his wife was on the second or third step when she fell and struck her face on the floor of the lower portion of the pontoon.  Victim was knocked unconscious for approximately five seconds and was awoken by her husband.  Victim was complaining of pain in her right wrist which later revealed to be broken.  Victim was transported by EMS to Saint Claire Regional Medical Center for evaluation.  The following day I spoke with Operator and he stated that she was in a temporary sling awaiting further evaluation.  I also explained to him over the phone that it was his responsibility to fill out his own boating accident report and submit it to our department for record.  I later examined the steps of the pontoon and noted that the steps were covered with a non-slip surface tape on the steps of the pontoon.  Operator also stated that his wife had consumed approximately two "Mikes Hard Lemonades" that day and did not drink regularly.  There were five other individuals on the pontoon at the time of the accident and no other individuals were injured but one passenger stated that she did see victim fall and her story matched the story provided by Victim's husband.  On July 18th, I contacted Operator to gain further knowledge of his wife and he stated that she was doing well but having outpatient surgery to place pins/screws in her right wrist and that there were no other injuries from the fall to report.
