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.
Cops can lie to you to extract a confession.

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).
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
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.
The legal System is setup to encourage this. The only way to prevent that would be independent audits of all investigations which would be both expensive, time prohibitive, and over time the "independent" auditors would be corrupted leading to the need for auditors of the auditors, etc etc etc
it is the "who watches and watchers" problem, you find a solution to this you let me know because you will be a very rich person.
Using thermal imaging to scan neighborhoods for the lights used to grow marijuana is considered a "search" by the courts and police have a warrant to do this. Let's say the police ignore this and go around secretly scanning cities without a warrant. They find out that John is growing weed in his basement, but they can't arrest him because this evidence is inadmissible. They follow John for a while and see that he interacts with Pete. Pete has a warrant out on him based on some unpaid parking tickets. So the cops arrest Pete, find weed, and get him to finger John as the source. Now the cops can get a warrant, search John's house, and "oh hey look there's all this marijuana growing here!"
This evidence is normally inadmissible as it was derived from an illegal search. It's very difficult to catch unless the police stupidly submit it to the court (as in the OP). Not using this tactic requires a high-degree of morality and/or oversight of police officers.
