subject's houseboat was anchored on sandbar at Enterprise Island.  Another watercraft was coming towards the sandbar on the starboard side of subject''s houseboat. The river current forced the watercraftt into starboard side of the houseboat. The watercraft struck subject''s houseboat two to three times. Victim  was in the water and got between the two boats. She lunged for the ladder but was struck by the watercraft three times, causing severe bruising/swelling of right arm/elbow, severe bruising on right thigh, and inside left foot.  The watercraft backed out and left the scene. Only information available is a 38'' Wellcraft cruiser, reddish in color with a white transom. The name on stern is Guilty Pleasures. United States Coast Guard check comes up empty. I checked with several marinas in the area. 
Missouri Water Patrol handled day of accident. They turned the investigation over to us approximately two weeks later for investigation.  
  
Investigation continues.
