See anything odd here?

Yes. There is no snow from the missing vehicle piled up on the ground next to the parked vehicles.

It's also unusual that no snowballs have been made from this first snow.

That car that just left has been spotted….

Yes, the rear tire tracks maintain track width throughout the turn but the front tracks do not.

Yes LaserWarrior, that's what I was referring to.

In the pic below the distance at Y is about 70 percent of the distance at X.

Here is an example simulated in Octave:

With the steering wheel cut at a fixed angle, a car turning through 90 degrees, starting at bottom right, would make the tracks as shown below. (Front wheels locations are shown as '*' at every 3.6^o of curve, rear wheel tracks are solid.)

Example: track=1, wheelbase=2, radius to inner rear tire=3.

Of course, in pulling out, the driver would be turning his steering wheel at various angles.

Probably the easiest way to recreate the motion of the car from the tracks would be to cut a rectangle scaled to the footprint of the car (track width vs wheelbase) and to overlay it where the four corners would fall on the tracks.

He let the car heat up while he cleaned off the snow and ice, this melted all the snow under the car....the snow was plowed before he left, but continued snowing leaving a thin layer of snow on the ground, the temperature outside is barely below freezing, and the heat from the tires and his shoes is enough to initiate the melting process leaving tire and shoe tracks....I don't see anything unusual....

Agreed, but the most unusual thing is the lack of snow between vehicles and the empty parking space.

There is an outline of a body buried under the snow beside the car on the right hand edge of the photograph.

If he drove in forward, he should have backed out, turned and gone forward.

If he backed in, he should have overshot the space somewhat, then backed in.

The tracks show him backing a long ways either coming in or leaving

After starting with a vehicle pulling in and out, I decided it more likely there was a vehicle and a trailer parked and the snow started falling. The footprints, on reconsideration appear to move from right to left toward the driver's side. When the vehicle pulled out you have four tire tracks, one for the vehicle and one for the trailer.

The photo is not very clear, but it appears that the footprints go AWAY from the car, not TOWARD it. Backward from what you would have when the car is leaving.

It is certainly ambiguous. I thought, at first, the footsteps were going away from the vehicle and later decided it was too instead. The reason I changed my mind was it appeared the tracks leading too or from were scuffed by the heal of the foot. The scuff marks appeared to me to be going from right to left. When I walk in the snow my heal leaves an imperfect heel mark with the snow behind the heal roughed up and the toe leaves a less marred track. I'm not taking a hard stand it just appears that way to me. Like you said we really don't have a clear picture to go by. Take care.
