Casey Anthony's parents attended a memorial for Caylee Anthony yesterday on what would have been their granddaughter's sixth birthday -- held near the spot in Orlando, Florida where her body was discovered in 2008.

During the memorial -- organized by a nationwide group for missing and abused children called "Bring Kids Home" -- George briefly spoke to the crowd of nearly 100 people.

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