Edit: I did misread it, sorry. It was Taylor who confessed. I wouldn't be surprised though, if the defense still uses the near-contempt and the overall lack of evidence to try to plead down or even still seek a dismissal.
If any one is interested in tracking it down, Derren Brown - The Experiments. Episode The Guilt Trip.

Added: Sorry, the point is that Im shocked that you are saying your police actually do this, in this way. When watching these shows its easy to assume that there is some extra trickery going on, so it cant happen to a real person in real life. Your case shows that it can.
I now have no reason to believe any of it is anything but actors and TV magic
I wonder if this will occur more frequently in an era when people can start to create highly realistic video that appears to be of a particular person performing a particular act (so someone can show you full-blown "surveillance camera footage" of you doing something that you didn't do).
Cops can lie to you to extract a confession.

Now that the defence knows about the stingray they will paint the rest of the case as fruit from the poison tree. They just need a reason to call the officer and ask about the stingray. The prosecutor can't withdraw the defences' questions.
The defence will merely reintroduce the evidence as evidence of police misconduct, this isn't going away anytime soon.
