As you wish, the following quote is from the Milwaukee Journal/Sentinel of 26 Dec 2007.
When members of the zoo staff realized a tiger was loose, he said, "the zoo shooting team was assembling," with tranquilizer guns. "But when police saw the weapon, they took it away. They had taken control of the scene."

I hope that clears up the issue for you.

Thanks! - it does give credibility to your claim that they took control of the tranq guns. Mia culpa
It still think it’s a HUGH leap to assume they executed a tranquilized cat, but we all have our biases that taint our assumptions. ;~)
