At her funeral at the First United Methodist Church of Orlando, Henderson, 21, broke down as he paid heartfelt tribute to his mother, almost unable to stand while he spoke.
"I never thought that her life would be ended right in front of my eyes," he said, sobbing. "My mother accepted everyone with open arms. She loved everybody equally, no matter what."

The funeral was also full of humor and colorful moments as Marquez-McCool's family remembered her life. She was repeatedly referred to as a resilient woman who was a family leader and a fighter.
