RedactedNarrative: On the 19th of June 2017 around 1:55 p. m. vessel #1 was traveling south towards Liebs Island. Vessel #1 turned to starboard and the tube carrying occupant #7 and # 8 entered a wake causing the tube to overturn.  As the tube was turning over occupant # 7 and #8 struck heads, causing occupant #7 to go unconscious briefly and enter the water. Occupant #8 did not sustain injuries due to the impact and once occupant #7 was rescued from the water, he was transported to Grant Hospital in Columbus.  At the hospital it was found that occupant #7 had a brain tumor (unknown until this time) and the collision with occupant #8 caused occupant #7 to go unconscious and suffer head injury.
