What "clue" does Jay find in Maning's office in “Not an Answer to the Question"? What does the clue indicate?

Jay finds a slip of paper in the bottom of Maning's desk drawer that contains a list of names with Jun's name on it. The writing is in Tagalog, so Jay is unable to read it but takes a picture of the note. It indicates that Maning might have had involvement in Jun's death.
