RedactedNarrative: On Saturday July 12 2014 at approximately 1645 I received traffic from dispatch by radio. TWRA dispatch advised me that there had been a boating accident with injuries that occurred on South Holston Lake in Sullivan County. Dispatch advised of a caller.

I arrived at Medical Express in Bristol with Boating Investigator at around 1730. Investigator and I spoke with Operator1 about the incident that occurred.

Operator1 observed a pontoon boat that was traveling in close proximity to his boat. The pontoon boat had its motor trimmed up as though it had rope caught in the propeller. Victim observed his left arm and noticed abrasions and swelling. The pontoon boat drove to Operator1''s boat and an individual asked if there was anything they could do.
