If his escaped had been planned and co-ordinated with accomplice, I believe he must have fled the country on 27 Feb 2008, the day he escaped the detention centre. How certain are the police when they say he acted alone? Assuming he is still in Singapore and unable to contact any of his accomplice, where can he hide? I don't know.
But I asked myself, if I were him, where will I hide? So I started to muse over this question. Where ever I may be hiding, the place has to be as far away from public view as possible. It should also be near sources of food and water... and near the coast as much as possible. Eventually, my thoughts led me to think of Choa Chu Kang Cemetery.
Firstly, it is not unusual to see anyone in a cemetery... even at night, especially in Chinese cemetery where punters are known to seek additional help for the spiritual world. Also, no one would take more than a glance at a stranger in a cemetery... especially if that stranger appears to be unkept. Who knows? The dilapidated stranger you saw may not be a human after all. Food is really not an issue, if one is not too choosy. There's bound to be some offering of food and drinks to the deceased. Well, if those are really not up to your taste, there's fruit trees among the forests surrounding the cemetery. Beyond the CCK cemetery to the western end is the sea. even if the Home Team were to comb the cemetery, chances are they may not be as enthusiastic about their searches compared to other places. Come on... cemetery gives everyone the creeps. He'll just need to bide his time and await for an opportunity to perhaps hijack a motorised boat from one of the kelongs near Serimbun or Kranji and off he goes... provided the Police Coast Guard failed to detect him.
Anyway, it's just my musings... there's still a lot of questions to be addressed... such as how could he get to CCK cemetery in the first place? How certain can he be that punters will not approach him and ask "Bang, you know which hantu gives good tips?" Or perhaps, he had been taken away by the pontianak hiding there... which is why the Home Team could not find him anywhere in this world...
To all the group troopers who are actually doing the work of searching - don't loose heart. We know you are putting in your best effort to look for him. Keep it up.
