The body of Natalie Marella, 26, of Ambler, was found off Little Road in New Hanover Township at 10:22 a.m. Wednesday.
In a news release issued Thursday, the district attorney's office said an autopsy was conducted, but the cause and manner of death remain undetermined pending the results of toxicology testing.
Marella's body wound found by a farmer mowing his field.
"I come up along and I couldn't believe it," said Mark Slater, the farmer who owns the property. "It just shocked me. I came in and got my daughter-in-law and she went berserk," Slater said.
They went back to the field for a closer look. The two had wondered if it was a mannequin.
They soon realized it wasn't.
"She saw a tattoo on the body, so she knew it was a person," said Slater.
Slater went on to say he and his daughter-in-law saw tire tracks in the field. He said it appeared as if someone backed up to the tree line and drove away.
The D.A.'s office said further information regarding the cause and manner of death will be released when available.
