George Anthony stood in front of the large crowd who held purple balloons in memory of the little girl's favorite color. They said  "We didn't know how we'd be perceived. It's just a great tribute to our Caylee. Other children have to come home, too. And that's what should be concentrated on now. We know where Caylee's at,"reported People magazine.

"Today it's for the other missing children out there that need to come home. Caylee is going to be the focal point that's going to bring [people] here but the other kids need to come home too," he said.

The purple balloons and butterflies were released Tuesday in the name of the toddler who last seen on June 2008, on what would have been her sixth birthday.
