Just got back from 2 week vacation in peru to find out that my pet sitter forgot to close the snake cage, and my 08 girl is gone

On top of like 3 other bad things happening to people i care about since I left, this is like the worst day ever.

I'm hoping the snake is still in the apartment, I can't see any way for her to leave the apartment unless she flushes herself down the toilet. Any advice? I'm going to try looking everywhere, picking up as much off the floor as I can, leaving her two hides out, and thawing out a rat to leave by one of the hides this evening.
