Cold Case Information for Tennessee Murders

Does anyone have any information on Cold Cases that happened in Tennessee or possibly in Pompano Beach area of Florida in the late 1960's? I am trying to get information on two cold cases that occured in Tennessee in 1969 for a Kathy Jones that was murdered in Nashville and Glenda Sirmans that was killed in the Knoxville area. I am also working on an old case of Betty Jean Necessary that was killed by Freddie Bowen in Kingsport, Tennessee in February 1970. Any information will be confidential and greatly appreciated.
