It was a normal shitty day at the zoo. While I was doing my normal walk around the koala section, I saw this elderly lady trying to take a selfie with the koalas and out of nowhere she collapsed to the floor and I quickly rushed to her to see if she was okay. When I got to her I checked on her pulse and nothing was there at all and I started to panic. I called 911 and told them this old lady has collapsed and I think she died. “Where is your location?” The officer said. “The zoo.” I replied. “Officers are en route to your location.” The officer replied. As I was waiting for the officers to come I checked for her pulse again and nothing was there. When the medics came to the zoo one of the medics pronounced she was dead at the scene due to a heart attack.
