State and Winthrop Police are investigating the discovery of a bag containing the remains of a toddler found on the shore of Deer Island around 1 p.m.
Assistant Suffolk County District Attorney Mark Lee said the body was that of a "a young child, small."
An autopsy tomorrow may reveal how the girl died, as well as her age and race. In the meantime, authorities are appealing for any information from people who may know of a young girl who has gone missing:
Perhaps most valuable will be assistance from members of the public who notice that a toddler-age girl is suddenly and without explanation missing from their community. Anyone aware of such a missing child may call the Suffolk County State Police Detective Unit at 617-727-8817 or Winthrop Police at 617-539-5806.
The Coast Guard, meanwhile, is analyzing the "drift pattern" of the waters around the peninsula to see if that might provide any clues where the bag came from, the DA's office reports.
