imagine a crime case..

V had rented e house(ang mo kio) which is on level 1 .. but she has a bad relationship with e landlord and e 2 sons..
1 day, e older son broke into e house with through e window when V is brewing coffee at a side table. Den because of e sudden break in.V toppled e coffee flask and e cup on e floor.e older son went across e room, grab hold of V and hit and punch her in e face.blood splattered on e wall.in shock, she quickly run toward e door for escape. the older son seeing that V is still alive run for her and give her e great hit in e head which made V collapsed. With hatred, the older son continue to kick and punch V in e stomach. Blood splattered again.Seeing that V is dead, e older son reach for e exit and escape, forgetting that he leave e fingerprint and blood stain on e door handle. He was seen in Jp in 20 mins with his younger brother.

Izzit possible? haha.. how did he travel from angmokio to jp in 20 mins? e STR show that its not e younger brother but it another son...so older brother? there were no glass piece at e window too.. why?

haha.. anyway..this is my forensic answer for e case studies... creative enough? e prof will be reading like so many different answer..haha
