According to initial police questioning of locals and nearby lifeguard staff in the area when the inicdent happened, Miss Chernobay had opted to dive and swim in the area that had been denied access to bathers. Whether she was aware of the restrictions or not was not diclosed although police did confirm that the driver of the speedboat did not see her in the water at any point.
There was no mention in police reports as to whether the driver of the boat would face charges.
