It is easy to be wise after the event but I am sure the first 24 hours after a disappearance are the most vital - and I am shocked that the police didn't think to go into the flat before now. Yes the neighbour said he/she saw the car but Greatnan could have been injured or worse in the flat and the the car could have been driven by a burglar. I know crime is rare in that area but there is always a first time. However, that is in the past and now it must be a case of finding the car.
