@Phil More puzzles, I say! More puzzles!
Currently waiting on Detective @dscheidt to report on (or pass) for Case 2.
(I believe Detective @yashima is currently consulting for another department, so will proceed without her report.)

After working on a spreadsheet for a while, the commissioner is delighted to report that your current rating is 98%! Great work in arresting the correct culprit so quickly! I have your next case prepared:
Case 3/8, dossier 5.
Time brackets:
(a) <= 3 mins
(b) 3-5 mins
(c) 5-10 mins
(d) 10+ mins
(x) not using a timer
5 suspects, 1 culprit, 1 lie
< 3 minutes
Dog is the culprit, and Dog is lying (just like Shark said!).

Speed is a double-edged sword (of Lady Justice, I suppose). Arresting the correct suspect is of paramount importance. The faster you can do that the better, but be warned that speed works against you if you get it wrong – the public may accuse us of shoddy police work if we arrest the wrong suspect without having taken the time for a thorough investigation of the evidence.

Dog is the culprit and is also lying.
The one lie must be either shark or dog. If shark is lying then dog is telling the truth, but neither iguana nor panther can be the culprit due to their own statement and peacock’s statement respectively.

Dog did it (and is lying).
In my symbology:
“yes/no” = culprit, “true/false” = statement veracity.
| id | c/h | ht | statement |
|---|---|---|---|
| pa | c | 178 | pe no |
| pe | h | 169 | pa or sh no |
| sh | c | 192 | do false |
| ig | h | 162 | ig no |
| do | c | 175 | pa or ig yes |
(And I could have saved some time by noting that I didn’t need the c/h or heights on this one.)
First test: assume sh true ⇒ do false. So not (pa or ig) yes = pa no, ig no ⇒ (pe, sh or do) yes
Add pa true: pe no, so (sh or do) yes.
pe true: (pa or sh) no ⇒ do yes.
ig true: ig no ⇒ do yes. (Adds nothing but is consistent.)

I’ve called that 5-10 mins. Which is still a strong score. (All correct answers score well!) Listed times should include all time needed to satisfy yourself that the answer is the one you’re going to submit.
Still pending for Case 3 is detective @mistercrayon.
To keep things rolling, after most detectives have posted a solution I’ll move to the next case, and the remainder can post their solutions for both the previous and the current case.

The commissioner frowns… Well, we had a bit of a hiccup there – bound to happen sooner or later. I’m afraid I can’t include the bonus for no false arrests this time around, and there’s a stern penalty to boot. Each new case has a larger impact on the squad’s rating than the last, so our rating has dipped to 85% (subject to improvement once all reports are in), but I know you’ll pull it back. I have to play by the book-that-I-made-up, though, as there are a lot of eyes on the squad right now. Not everyone in the upper ranks is convinced that we should even be solving animal crimes remotely by way of an online forum! We have little choice, though, if we’re going to keep news of the catastrophic computer glitch, which scrambled all of our lie-detector test results, out of the newspapers!
Despite the speed bump, you’ve all shown me what you’re capable of, and the Superintendent has eaten dossier 6, so we’re going to step things up just a notch:
Case 4/8, dossier 7.
Time brackets:
(a) <= 3 mins
(b) 3-5 mins
(c) 5-10 mins
(d) 10+ mins

5 suspects, 1 culprit, 1-2 lies

So there is either one or two lies?

Yes, that’s correct – one of the lie detector results was very ambiguous!
