Art of Murder The Hunt for the Puppeteer

Does The Hunt for the Puppeteer belong on the Darkside forum?
Have gone back over the game so far, retracing every step. Clicked on the ? key and rechecked all of the places it shows a question mark in each scene.
I am stuck at the door by the policeman. Tried clicking on him but "end of conversation" comes up. Even though the fuse box is there, there is nothing to do. Clicking on it is only a message "no wonder there is no light..."
So, at this point it's click on the door to the left of the policeman, but the door won't open.
Does anyone know how I can get through the door?
Thank you!

This means you haven't finished taking all the evidence in that room.
See if you have all the pictures needed and picked up evidences.

MaG, you are fast. I was reading your walkthrough

Hi L4L.

ok thanks! I have checked the camera several times and see that I apparently have 6 pictures but do not know how to view them?
I'll try again!
Thanks!

Good luck.
