ST. AUGUSTINE, Fla. -

The final autopsy is not yet complete.

Parchem, 67, went missing April 5 when she failed to show up for work. Her body was found three weeks later in a wooded area just south of the St. Johns-Flagler County border.

Parchem's daughter, 39-year-old Lilly Ann Chavez, has been named a person of interest in the killing. She bonded out of the St. Johns County jail Sunday on unrelated weapons charges.

Deputies arrested Chavez (pictured above) on May 4 after detectives said they found nine guns in the home she shares with her boyfriend.
