BENSALEM, Pennsylvania (WPVI) -- Authorities have identified the skeletal remains of a woman discovered 33 years ago at the old Publicker Distillery in Bensalem, Pennsylvania. On Tuesday, the woman was identified as 17-year-old Lisa Todd from Philadelphia. Authorities are still trying to figure out the circumstances surrounding her suspicious death. "Pregnant ladies don't just fall into wells and die. Something happened," said Bucks County District Attorney Matt Weintraub. Authorities said in October 1985 an unidentified woman was reported missing in Philadelphia. In 1988, her skeletal remains were found in a well that used to be the Publicker Distillery along State Road in Bensalem.
