RedactedNarrative: On June 17 around 10:45 I was notified of a boating accident on Logan Martin in the Riverside area. Once on the scene I met with Capt.. We were advised that one victim had been transported to UAB in Birmingham in critical condition and the other was transported to the local hospital in Pell City. It was told to me that the vessel impacted the railroad bridge pylon and continued on. The vessel ran ashore approximately a quarter of a mile down river. The emergency cut off lanyard appeared not to be worn and was found wrapped around the throttles which were in the full throttle position. We were unable to determine the operator of the vessel at the time of the accident.
