Authorities on Tuesday said a fourth woman whose body was found behind a row of motels near Atlantic City has been identified as a 20-year-old from Pennsylvania.
Molly Jean Dilts had last been in touch with her family in Blairsville, Pa., on Oct. 7, authorities said. A missing persons report about her had been filed and Dilts' fingerprints were used to learn her identity.
An autopsy could not determine her cause of death.
Dilts was the final woman of the four to be identified since their barefoot bodies were discovered near the Atlantic City line last week.
The other women have been identified as Kim Raffo, 35, Tracy Ann Roberts, 23, and Barbara V. Breidor, 42. Raffo was strangled. Roberts, whose last known address was in Atlantic City, died from asphyxia, but authorities do not know exactly how she was killed.
Like Dilts, a cause of death could not be determined for Breidor. Authorities said all four deaths are being investigated as homicides.
Raffo's body had been in the ditch for a couple of days. Authorities have said the body now identified as Dilts had been there for up to a month.
Authorities said the other three women had police records involving prostitution.
