Another interesting case. A young girl's skeletal remains were found on September 13, just days before Dulce went missing. The article shows a picture of what she could have looked like. The remains were found in Smyrna, Delaware.

So it's definitely not Dulce but it appears she had been dead for quite a while as only bones were recovered in an open area near softball fields. LE says she is probably between 2 and 5 years old and suffered from a chronic illness or illnesses. Smyrna is about 65 miles from Bridgeton across the Delaware River. Second article identifies the field as Little Lass softball fields.

IMO it's worth keeping an eye on the case. I haven't checked to see if there's a thread for her here but I'll take a look a bit later.
