Joe Bohannon asked Pat Brown to explain what it is she actually does, what is her job ? Pat explained she is a criminal profiler, she looks at the facts of the case and this helps the police to follow leads, look in the right direction and saves wasting time. British profiler LEE RAINBOW did just that on the McCann case, he concluded as Gerry McCann was the last person to see Madeleine ALIVE ( looks like Lee also came to the conclusion Maddie died in the apartment, or was certainly dead) McCann MUST be investigated, we may be looking at a homicide.
