A doctor from Orlando Regional Medical Center posted a powerful image on his Facebook page following the massacre at Pulse nightclub.
Dr. Joshua Corsa, a senior resident at the hospital, posted the image of his brand new sneakers covered in blood, as well as a basket of bloody scrubs.
In the post, he wrote: "These are my work shoes from Saturday night. They are brand new, not even a week old. I came to work this morning and saw these in the corner my call room, next to the pile of dirty scrubs.
Remember the victims of the Orlando tragedy:
"I had forgotten about them until now. On these shoes, soaked between its fibers, is the blood of 54 innocent human beings. I don't know which were straight, which were gay, which were black, or which were hispanic. What I do know is that they came to us in wave upon wave of suffering, screaming, and death. And somehow, in that chaos, doctors, nurses, technicians, police, paramedics, and others, performed super human feats of compassion and care."
Posted Monday, the image has since been removed, but it was recovered by other Facebook users.
He also wrote: "This blood, which poured out of those patients and soaked through my scrubs and shoes, will stain me forever. In these Rorschach patterns of red I will forever see their faces and the faces of those that gave everything they had in those dark hours."
See how the world honored the Orlando victims:
