Reporter: A moving final farewell for George Floyd in Houston. I believe I believe that a change is gonna come Reporter: Hundreds of family and friends gathering to remember Floyd -- the child and then the man they loved long before the movement. The world knows George Floyd. I know Perry Jr. Reporter: The star high school athlete with the big smile and sense of humor. A gentle soul. A loyal friend. A protector.

Even though for one mama, all mamas began to wail. Reporter: Just a day after meeting with the family, Joe Biden sharing a video message and these words for 6-year-old Gianna. Daddy is so proud of you. No child should have to ask questions that too many black children have had to ask for generations -- why. Why is daddy gone? When there is justice for George Floyd, we will truly be on our way to racial justice in America. And then, as you said, Gianna, your daddy will have changed the world. Reporter: A regular man from the streets of south Houston, whose legacy may now be a catalyst for change. If four black cops had done to one white what was done to George, they wouldn't have to teach no now lessons. Until we know the price for black life is the same as the price for white life, we are going to keep coming back to these situations over and over again. We should recognize the mother of trayvon martin. Will you stand? The mother of Eric Garner. Will you stand?
