[what's up]

No footprints (in the snow)

The snow was not waist-deep as the police led you to believe.

In fact, it was not even 3 inches deep.

In fact, the yard had large snowless patches and there was NO SNOW just outside the window or on the sidewalks.

Thus, no footprints were left by the killer.

“Thus, no footprints were left by the killer.”

What about the cobwebs inside the windows that were not disturbed or a motive?
