Lake City police are looking for a woman who left a note indicating a bomb threat at Mercy Medical Center.

An employee told police that an older woman wearing a sheet over her head walked into the lobby and left a handwritten note on the counter at 6:46 p.m. Monday.

The note read, "everyone must die to pay the price so I going to blow it all up."

The woman then left in a dark colored minivan or station wagon.

Police searched the office area and outside the building and found nothing.

The woman is described as having dark hair. She was last seen wearing a blue shirt.
