Also, I know Google guy is several years old but down on St. Landry on the corner of Henry, is a four door Z71 parked in the driveway on St. Landry side. Maybe check and see if the truck and owners still live there, still have the truck and if anything seems suspicious?
I do think she is a blur on the photo behind the hooptie in the St. Landry/Hooptie photo.
The back tire just jumps out at me. So, I think she made it down Landry to her usual left and towards Johnston. She was moving at a pretty good clip, she had to stop on purpose, maybe for a stop light?
I also -cannot get myself to leave that hospital alone...an empty hospital just seems so vast and kind of cut off from sight or suspect. It seems kind of cliche' like Whiskey Bay. Like out of a bad novel. But, I think we are dealing with an older demented/mentally ill person and not some perverted drunk oil rig guy. It needs looked at again.. Hospital rooms, laundry rooms, utility closets, basement?
Is that a coulee that runs underneath the hospital?
