Heartful appreciation to Rani, Carang, Mummymoo and Elle - thanks for all of your suggestions. So far, I have
1. changed the locks,
2. notified the guard about her disappearance
3. trying to get the Head of Security to change the password of the front door
4. Wrote the letter to Immigration - will post/fax tmw morning
5. Done the police report (yesterday) but will file for 'missing person' tomorrow
5. Valuables - nothing missing so far !
What I still find difficult and struggling inside me is that, somehow I still care very much for her - she had only worked for me for about 9 months and we had shared a lot during this time. I even gave her a free ticket to Cebu as a X'mas gift so that she was able to spend her X'mas with her children after being away for 4 years. I am also a mother and I feel very sorry for her being away to work and having to support her cheating husband.
I gave her a laptop to use so that she was able to communicate with her kids - I've been restoring the items in the Recycle Bin - there is no proof so far of her planning to leave or pictures of her with 'guys', but there are some googling on 'love and kisses' and also Indian songs and Nepali stuff - I wonder if she had fallen in love with an Indian/Nepali and 'eloped'!
It's strange as there was no need for her to do so - if she had found someone really nice, I would be very happy for her and want only what is best for her.
Btw - she owed me over HK$8,000 for buying a laptop for her kids. She also owed neighbor's helper HK1,400 and few hundred from the guard - all based on lies. The ironic thing is that, we shared a lot about Christianity and God !
I wouldn't have guessed in a million that she would do such a thing.
Somehow, I still worry about her, even at this moment.
However, the laptop is somewhat helpful in tracking her and a useful tool to discover more things about her.
Thank you all for listening and offering your advices.
