3 incidents have happened in our class lately
1.shah's key was stolen on monday
2.linken's hp was stolen during recess on thursday
3.On saturday,nicholas hp was stolen
And cherie's mp3 went missing on monday

out of 39 ppl in our class,i've got a hunch that 1 out of these 39 stole nicholas, lk and shah's most valuable items..
i deduce that-
first of all,he/she must be close to them(near)
secondly,they must have full access to the class 2F
thirdly,they must be swift in taking things

I believe that the thief also have a good classmate relationship with every1 so that he/she will not be suspected.
To the victims:if u know anyone that had bear a grudge with you before,or u bullied him/she b4,he/she can be a crucial suspect.

Summary of that incident on Saturday about the stolen phone of Nicholas:
Nicholas was very sure that he place his hp back into his bag during the last lesson after his phone dropped on the floor.He still saw his phone.Within seconds,after nicholas walk away(walk way part i not very sure),hs phone went missing.We ransacked the whole class,but we didn't fnd a single thing.So it had to be stolen.

Reminder to whole class:until the culprit was found,I beseech you not to bring ur phone and mp3 player to school.And always keep ur most valued things with you,for example,keys,money and your own bag.
