Friday marks one week since a Michigan gas station clerk disappeared on the job and police may be back to square one.
A person of interest in Jessica Heeringa's possible kidnapping has been cleared.
The woman's parents have also submitted DNA for testing if needed.
The 25-year-old was last seen at the Norton Shores gas station she worked in on April 26.
