Why didn't he hire a genealogist?

So I'm sitting here looking at my own records and furthering my research with NPR's Weekend Edition Sunday on the radio in the background.  They just played a story about Benjamin Kirk, an amnesia patient.  The story went through a few of the different methods that he used to try to find his past, including a DNA test and a check for his fingerprints in criminal databases.  But there's no mention of the one professional that is trained and finds people's histories on a daily basis.  He should have hired a genealogist to find his past!
