Attached are two, Google Street View, images of the M&M gas mart. The first is taken from the intersection of Carlisle Road and Hwy US 51, looking north.
If you zoom in, until you can no longer use the google zoom, you will get a clearer picture of the locale.

The second image is taken from a position slightly north of the first image in order for you to zoom in even closer than the first.
What you will notice in these two images is that Jessica Chambers ( who lived farther north on Carlisle Road) may have driven down Carlisle at 6:24:xx pm Dec 6, to the left hand dirt road, near the puddles, and then proceeded to make a circular drive around the outside pumps in order to position her Kia at 06:24:39 on the inside pumps. Had she done this, she would have been facing SE (as depicted in the CCTV videos).
At 06:32:xx pm, Jessica then leaves M&M driving into the darkness, headed SE.
However judging from these two Google Street Views, it is clear to me that there is
no conclusive evidence available to suggest that Jessica then either
- continued out, onto US 51, heading north or south, or
- retraced her exit from the pumps and returned again up Carlisle Road, heading north.
Simply put, we just don't know what direction she took, or where.
The fact that the next 90-minutes remain unaccounted for, plus her purchase of $14, and her statement that she was head "somewhere" means to me that we should take into consideration any area within a radius of a maximum 70 miles or a minimum 25 miles (1/2 of estimated $14 gas purchase + Kia mpg equals maximum mileage reduced for a roundtrip return).
With respect to the maximum mileage divided by 1/2-time (45-minutes of 90-), I believe we have an unacceptable speed (93.33mph) and this would have left her with no time at her destination before she immediately needed to return in order to arrive at Herron Rd. 90-minutes after she screamed away from the pumps. Thus it would be my argument that the maximum distance is absurd.
Even a more conservation 45mph speed multiplied by 0.75 (3/4 of an hour) leaves us with 33.75 miles covered; yet no time for being there.
Consequently I would suggest that we should concentrate on a radius of 25 miles from M&M. This would leave us within a small area as well as a short period of time in order to drive outbound and then to return inbound to Herron Road.
Batesville is easily within this radius. Both Clarksdale and Grenada are not. Enid Lake (Yalobusha Co.) and Leah's House (in Oakland) are, but Memphis TN is not.
