Law enforcement officials say that they still do not know what killed a Trenton woman whose body was found on a city street several months ago.

The Mercer County prosecutor's office said Wednesday that the cause and manner of death of 43-year-old Lillian Duran, of Trenton, remain undetermined following an autopsy by the Mercer County Medical Examiner’s Office.

Authorities said a witness alerted them Sept. 4 about the bag on Lamberton Street in Trenton, and police confirmed there was a body inside. It wasn't clear how long the body had been at the site before it was discovered.

Prosecutors said the case remains open, and anyone with information is asked to call the county homicide task force at 609-989-6406 or Trenton police at 609-278-8477.
