Underwood, 64, was on a call working to unblock a culvert when he collapsed and died.
MetroNews affiliate WVOW in Logan described Underwood as a community icon who not only led the fire department but also ran the Lake Community Center.
He was a 1968 graduate of Logan High School where he was a standout athlete.
Southern West Virginia wrestling fans may also remember Underwood as the “Cuban Assassin.”
Evans Funeral Home in Chapmanville is in charge of arrangements.
