My guess is well after for these reasons.
Here is the body with the tarp in the stretcher about to be bought up.
Notice the green shade, 10+ people.
Now they are packing up.
Now they are walking away
Green tent should be visible in this last shot as it was setup above the first pylon.
Morning, have been thinking about these photos all night. The light is much better in the second & third & I wonder if they are setting up rather than packing up. It was getting later when they actually removed Allison from the scene and dark before they left. The green tent would have been used for primary examination. The ambos in blue suits are wearing gloves suggesting they are about to be doing their job. Others are looking over - perhaps deciding how to best approach. The tide looks high in the second & third & I wonder if they waited until it dropped to get better examination of surrounds before disturbing anything. Thanks again for the photos, passed over the bridge & again thanked those who placed the flowers, both sides now are a balanced & beautiful tribute.
