Richard Simms, NewsChannel9 - CROSSVILLE, Tenn. - TWRA investigators used an underwater drone to recover the body of a missing fisherman on Center Hill Lake Thursday.
Scott Northrup, 66, was a retired chemistry professor and the faculty advisor to Tennessee Tech's bass fishing team.
Northrup was reported missing around 5:30 pm Wednesday when he had not returned home from a fishing trip when expected. His truck and boat trailer were found at the Hurricane Creek boat ramp and his boat was found on the lake around 7:30 p.m.
TWRA investigators said the boat was afloat with the trolling motor down. He said it appeared that Northrup had fallen out while fishing, although at this time it is unclear if some other health-related issue may have involved.RELATED: Search underway on Center Hill Lake for missing fisherman
