Solution to: Virtual and vivid ambiguity

Jack: As you can see the picture of the victim in crime scene :

And the picture of the girl in stranger's photo:

If you see it carefully, you can see the mole(birthmark) on the victims face is on the left in crime scene and mole is on the right in stranger's photo.
As I entered the house I saw mirror pieces on the floor of the house:

As the small details tell the truth, clearly the stranger must have taken the photo in the mirror(only possible way of changing mole position on the face). This means that that crime must have taken place at 9.00 instead of 3.00 in the noon. According to forensic report, it must have taken place at night 9.00 and the killer must be a right hand person.

So the killer is HUSBAND! arrest him!
