The day started out with all of the groups teaming up
and returning to the crime scene to finish processing. We processed the
body and we also finished up some trace evidence with a little
fingerprint dusting and some blood splatter photos.
Crime scene revisited sheds light on new evidence.
Then we sat down to plan our excavation lay out for
the day which included setting up a north line and planting flags in the
ground to indicate true north. We all came together in a straight line
to begin the fingertip search to see if we were able to locate soil
disturbances, vegetation signatures and evidence of human life. We
planted almost ninety flags in our search area.

After taking a short break for lunch we broke into
groups and began to survey the land by using our compasses and
bariums to locate correct angles. We then spent some time using the
ground-penetrating radar (GPR) machine to try and see if we could get
electromagnetic responses from the ground to show us weather or not the
top of the soil was shallow. The readings of the GPR indicated exactly
were some good places would be to start preparing our grids. Every group
was assigned to a grave site that we had to properly grid out, establish
datum point, and began to measure all visible evidence within our site.
