Thanks for clarifying.
Using google maps, I have viewed images of the location where the bag was found. What can be learned from those images?
(1) The back-pack was placed where it could be easily discovered.
(2) There are only two streets that allow access to the neighborhood in which the back-pack was discovered.
(3) The back-pack was placed at a point where the person who left it there would be least likely to be seen by a resident: no window looks out onto the sidewalk where the back-pack was found.
The person who left the back-pack did so more than 36-hours after the victim's disappearance (based upon published statements aboutwhen the man who found it believed itwas not there, c. 6:45pm Saturday, when he and his wife left their home). Assuming that this person or persons who committed this crime knew that they would be implicated if stopped by police and the back-pack was found in the person or person's possession, then the perpetrator(s) was/were taking significant risk to drive (assuming a car was used) to this location and leave the back-pack.
Has anyone given any thought to the possibility that the perpetrator(s) wanted to send a message to police, and that the message was so important to the perpetrator(s) that the risk of being caught with the back-pack was out-weighed by the desire to be certain that the police should find the back-pack?
