A slam dunk is something normally associated with basketball, but it is also a term used by the police. It means an open and shut case. One about which they are certain of the perpetrator. And one where they are confident of a conviction.
There is only one problem with a slam dunk case. Sometimes, what they are investigating might not even be a crime.
This was the dilemma in the case of Felicia Tang whose death on September 11th 2009 was unexpected, unusual and extremely violent. Within hours of their involvement police had their man, and they could sit back, gather evidence and wait for the conviction that would look great in their statistics.
What they would find out, however, was a mystery most unexpected.
