Investigators recently completed a DNA profile of Baby Doe, the toddler found dead last month on Deer Island. Her DNA, however, was no match for anything registered to the National Center for Missing and Exploited Children's database.

The search will not end there, and the girl's DNA profile will now head to a lab in Texas for more advanced testing. That lab has a wide database of aggregated DNA profiles which they can compare against Baby Doe's profile, Massachusetts State Police detectives said.

Officials are sharing the information with law enforcement across the country with the hope that the DNA profile will lead to an identity of the little girl, whose body was found in a trash bag on Deer Island.

The new piece of information comes just days after 84 billboards were displayed across Massachusetts with the composite image of the girl put together by State Police.

Dr. Robin Cotton, a biomedical forensic scientist at the Boston University School of Medicine, said that DNA profile will be most effective when police name a suspect or person of interest.

"The number of random people in the population that may have half certainly wouldn't be enormous, but it would be bigger than you'd want to have for investigative leads," she said.

Baby Doe is believed to be four-years-old, about 30 pounds and three-and-a-half feet tall. She has brown hair and eyes and is believed to be white or Hispanic.

The girl was wearing white leggings with black polka dots when her body was found last month. A zebra print fleece blanket was in the bag with her body.

Officials still don't know how she died, and are awaiting results of toxicology results. As always, anyone with information is urged to contact police.
