I leaned down and looked into the black plastic liner.

Two thin paper backing sheets lay at the bottom, crumpled into small white balls.

I reached down, picked one up, and smoothed it flat on my palm.

The blue text across the top read *Sterile Cotton Buccal Swab – Medical Grade*.

The clear plastic backing had been peeled off and thrown away less than an hour earlier.

I turned the paper over and read the small black stamp near the bottom edge.

It gave the name of a private medical testing lab on Tenth Avenue in downtown Bellevue.
