WEMB is a radio station which served the Tri-Cities region of Johnson City/Kingsport/Bristol in Tennessee and Bristol in Virginia.
Shelton told disc jockey Charles "Chuck" Ray he wanted to be put on the air.
A SWAT Team from nearby Johnson City was brought in and ordered to surround the station.
At the request of his wife, who spoke to him through a megaphone, Shelton walked out of the building and surrendered to police custody.
In 1966, the station moved offices and broadcasting headquarters to Riverview Road, just south of Erwin, due to severe flooding of the Nolichucky River.
