How much time do you have to save Rebecca?

I couldnt save her....I did remember searching everywhere but nothing, so I though she would appear later on. Now I know where she was but I wonder what triggers her death

If you didn't kill the hunter when you heard the noise in the Spencer room in time, she dies.

You can't take too long and need to take certain pathways to save her.

It is not exactly a timer only, it counts the number of doors you go through. After a while, she is marked as dead.
IIRC, it is ten minutes, but I cannot remember the door count limit.

Thanks I guess my question was more technical rather than logical
