The mud on the suspect’s pants was from the criminal
scene
All results came to the conclusion that the mud on the suspect’s pants
was from the criminal scene (Fig. 3). When all ZOTUs were used and
singletons were considered, about 56.19% of the diatom ZOTUs in the mud
on the suspect’s pants were trackable to sample Site 1-1, 7.44% to Site
1-2, 23.90% to Site 1-3, and only 12.47% to other sources (Fig. 3A).
If singletons were not considered, the percentages were slightly higher,
65.75% to Site 1-1, 1.34% to Site 1-2, 25.18% to Site 1-3, and only
7.73% to other sources (Fig. 3B).
When only annotated ZOTUs were used and singletons were considered, the
percentages were 65.99% to Site 1-1, 2.31% to Site 1-2, 25.91% to
Site 1-3, and only 7.73% to other sources (Fig. 3C). When singletons
were not considered, the figures were 67.08% to Site 1-1, 0.81% to
Site 1-2, 24.42% to Site 1-3, and only 7.69% to other sources (Fig.
3D).
