This case makes me crazy.

If they have a way to track people outside the building by camera and can track the use of 'pass badges' inside they must have known she was still inside the buidling somewhere.

They would have noticed anyone moving a large bundle out of the area via tape/camera if the killer had tried to move the body out of the building.

If she had been dumped into a trash bin, someone emptying the bin would/might have noticed a large bundle in a bin.

The top she was wearing was GREEN - an easy color to spot on the tapes.

I just have some questions about how and why it took the cops that long to find her, especially with dogs in the building.
