Colorful Drama

This morning when I stepped out for a walk I noticed there was a group of people one man was pressing on a man's bare chest as he lay on the ground. Then I heard sirens. I watched seven emergency medical technicians pile out of a little red ambulance in matching blue shirts. Was it a heart attack, stroke, overdose, who knows. They brought out a yellow stretcher and they lifted the man onto it and brought him into the ambulance. The vehicle was motionless for a while. Was he alive or dead? What's going on? My dog pulled me to continue on our walk.
