For years, some law enforcement agencies have replaced the faces of traditional playing card decks with images of missing and murdered people and distributed those cards in prisons hoping inmates would come forward with information needed to crack these cold cases wide open. Now, audiochuck is dealing you in. Each week, we will be working with investigators and family members to bring you the details of some of the coldest cases from around the country in hopes that someone listening can finally bring these victims the justice they deserve.

Ronda Taylor and Bonnie Ryther (the King of Clubs and 9 of Diamonds, Florida)

Our cards this week are Ronda Taylor and Bonnie Ryther, the King of Clubs and 9 of Diamonds from Florida. 

There is a man serving a life sentence in a Florida prison for his part in the 1989 murder of a 29-year-old pregnant woman named Donna Callahan. Two brothers were ultimately convicted for her abduction – and each of them pointed to the other as the ultimate preparator. But only one of them would go on to confess to over a dozen other murders. That man is now considered, by some, to be one of the deadliest killers on Florida’s Gulf Coast.  And if his original confessions are to be believed, then not one, but two Fort Walton Beach cases could be closed. Right now, one detective is making it his mission to find out once and for all: Can he prove Mark Riebe is the serial killer everyone thinks he is? And was he–or someone else entirely–responsible for the murders of Ronda Taylor and Bonnie Ryther? 

  •  If you know anything about the murders of Ronda Taylor or Bonnie Ryther in Florida’s Gulf Coast, you can contact Detective Wilson directly at 850-797-2458. You can also call the Emerald Coast Crime Stoppers at 850-863-TIPS.
