State police spokesman David Procopio tells The Boston Globe that people have provided information on other missing children, too.
Officials released the image Thursday in an attempt to generate clues about the girl's identity, which remains unknown.
Officials believe the brown-haired, brown-eyed girl was about 4 years old. Her body was found June 25 on Deer Island inside a plastic bag that also contained a black and white zebra-print blanket.
