On the day that Caylee Anthony would have turned 6, her grandparents held a public birthday memorial for the little girl near Orlando, Fla., on Tuesday.
Attendees released purple balloons (her favorite color) and butterflies in Florida near where the remains of Casey Anthony's daughter were found.
Several hundred people attended the memorial.
George and Cindy Anthony held hands and wore T-shirts that read, "You Will Always Remain In Our Hearts, Caylee Marie Anthony 2005-2008."
George Anthony 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."
"That's what should be concentrated on. We know where Caylee's at."
One month after Casey Anthony was acquitted of murder, she remains in hiding for her own safety. She was spotted in Ohio early last week.
