CABRERA: some serious questions are being asked tonight about how the Topeka Kansas Zoo handles its tigers. This after a 7- year-old male named Sanjiv attacked a zookeeper worker this morning, sending her to the hospital with puncture wounds to the back of her head, neck, arm, and her back. It's not sure why the worker and that animal were in the same space at the time. The zoo says it's investigating but it appears the rare Sumatran tiger was not at fault and won't be euthanized. The Topeka Zoo reporting the zookeeper is now in stable condition tonight. Also noting that Sanjiv, the tiger that attacked, recently fathered four critically endangered tiger cubs as part of the zoo's species survival plan. That does it for us. Thank you for being here. "Chasing Life" with Sanjay Gupta starts right now. Happy Easter.
