Murder investigation

Detective Leong was involved in a murder investigation. In the suspect's house, the only thing he found useful was a password protected computer and a piece of paper nailed to the wall. He suspected that the paper was the answer to accessing the computer, but could not figure out what the password is.

Written on the paper was "ShE IS ILL".

Do you know what the password is?

HINT: There is no spelling mistake. You might want to write it on a piece of paper.
