That’s what I’m wondering too. But it sounds like the co workers didn’t know who he was. Worrisome.
It doesn't sound as if they knew who he was according to the newschannel10 report:
Video surveillance shows Gilbert walking to the Plains Dairy Parking lot just before 8:00 p.m. that night, and co workers may have seen her talking with a Hispanic male in the parking lot around the same time.
I wonder if this man was picked up on video surveillance at all that evening?
