Yes. I live in Houston with similar humidity. If the bathroom door is shut the shower will stay wet. I must leave the door open and vent on. In super humid weather it will stay wet no matter what is done.I've tried to think of different scenarios about how Jen was taken and I really think she was taken by someone known to her. If she didn't answer a knock the neighbour I cant imagine her answering to a stranger late that night.
I think the previous comment about someone watching her movements and
would know this night time block would be opportune because no one would be looking for her is spot on.
I also googled chloroform as this was a previous theory for no signs of a struggle in the condo and it takes approximately 5 minutes of being held to the face to render a person unconscious. That is a long time when you count it and I cannot imagine this scenario if the fbi profiling height is correct for poi and based on Jens height and strength including moving her down stairs. It's possible but unlikely.
If the offender is known then an old boyfriend or co worker for example would have an update on the case because perhaps they were contacted eg co worker msg by another co worker to say have you heard Jen is missing or family friends contacting people could give this person a heads up to move the car otherwise this is jst sheer luck that the Kesse's arrived just after the car was moved. I don't believe the offender hung around her apartment until morning too risky with workers and leaving evidence behind. All imo only.
If the bathroom door was closed (Kesse's cant confirm or unconfirm) and based on weather conditions for that date is there any possibility the shower could remain wet?
