Massachusetts authorities say they've received hundreds of tips from across the country after releasing a computer-generated image of a girl found dead in a plastic bag in Boston Harbor.

State police spokesman David Procopio told The Boston Globe  that people have provided information on missing children nationwide, and the state police Facebook page that includes the image and other information has received millions of views.

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.

Procopio said investigators already have ruled out tips about several missing child cases. (Associated Press)
