Two stories of senior citizen serial killers are profiled here. Dr. Harold Shipman and John Glover. Shipman was a doctor who is considered one of the most prolific serial killers in history. He would ultimately be found guilty of fifteen murders but many more are suspected. His total victim could be as high as 250. John Wayne Glover was a serial killer convicted of six elderly women and was dubbed the "Granny Killer" by the press. Like Shipman, his estimated death count could be considerably higher.
