Who killed Stella?

Hard, 9 clues

7 people were in the building, and one of them did not come out. Everyone was on a different square, never two in one row or one column, on the 8 wide by 7 tall plan. Work out where each of them was, the victim included. Whoever was alone with the victim did it.

The cards

Pick a person by tapping the photo on their card, the victim too. Then tap a square to put them there, or drag the photo onto it. At this difficulty the game does not cross off rows and columns for you, unless you switch on Cross off for me. Holding a square, or switching the pencil on, makes a note. Keyboard: Enter places, Shift and Enter makes a note.

Good to know

Beside: on one of the four squares directly above, below, left or right, in the same room. Diagonally does not count, and neither does through a wall. A window or door in the wall of your square is beside you.
Alone: nobody else in the same room, the victim included. Alone with someone: those two, and nobody else in that room.
In a corner: on a square of that room where two of its walls meet. The end of a narrow corridor counts too.
