Loose all stamina and sanity at the same time?

By Negalith, in Arkham Horror Second Edition

If an investigator is reduced to zero stamina and sanity, such as by using an Elder Sign with only one of each left, what happens to him? Hospital, Asylum, devoured?

If you ever reach 0 sanity and 0 stamina at the same time, or your maximum sanity or stamina reaches 0, you are devoured.
