The document provides guidance on collecting, analyzing, and documenting botanical evidence at crime scenes. It discusses securing the crime scene, taking photographs and videos, searching for plant evidence, proper storage and drying of specimens, documenting the evidence through notes, sketches and chain of custody forms, analyzing pollen evidence, finding an expert botanist, transporting evidence safely without contamination, proper retention and disposal procedures, and a step-by-step method for collecting plant specimens at a crime scene. The document serves as a reference for the entire process of obtaining, analyzing, and reporting on botanical evidence in criminal investigations.

Initial crime scene notation
1.Secure the Crime Scene
2.Record the Crime Scene
3.Photography:Crime scene photography
is very important
“A picture is worth a thousand words
figure
Videotape – the use of videotape is being
implemented on a widespread basis in
crime scene investigation recently

Where to search for evidence
Many people do not know that pollen
can play an important role in exposing
the crimes, it is in most cases the
investigation get the equivalent of only
ten grams of dust, It is the amount of
hard to see it, and be the source of this
dust is usually inside a bag person or
clothes or murder's car or even from
inside the bomb,

5. SANA
Storage
Plant evidence should be stored in cool dry
area
Pressing and drying
Specimens are pressed flat and dried
between sheets of absorbent blotters or
semi-absorbent paper such as newspaper
The plant should be carefully laid out
between the drying sheets, as their form at
this stage largely determines their ultimate
appearance. The flowers should be spread
out with the petals carefully arranged.

Documentation of botanical evidence
Crime scene documentation is necessary to preserve the
character and manner in which evidence was located and
collected from a scene, and in showing the relationship of that
evidence to the overall scene and other evidence. Proper scene
documentation involves multiple formats, such as general
note taking, photography, videotaping, and sketches and
diagrams. Each form of documentation is meant to
complement the other.

How to have botanical evidence analysed
pollen can be used to connect a suspect to a victim or scene.
Pollen is a powder-like substance released by plants as part of
their reproductive cycle. Since it is produced in large volumes
and is easily transported by wind, pollen grains are often found
on clothes, hair or skin. If investigators find a rare plant type
near a murder victim, the presence of its pollen on a suspect
could place them at the scene. Even for common plants, each
environment has its own unique combination of pollens, and
this 'signature' can link an individual or object to a location.
Pollen signatures may also indicate that a body has been
moved or suggest the type of area where the original crime
took place.

Where to find a botanist
Virtually all community colleges, and universities have a
botanist on their faculty. Botanists work in laboratories, offices
and in the field, both alone and with other life scientists. They
may work irregular hours and live in remote areas when
carrying out research.

9. SANA
Type of cases
laws list some plants used as
medicines or drugs or those believed
to be noxious weeds as illegal.
Therefor possession of any these
listed plants is illegal , but the first
step is identification, which often
demands someone with special
training for example Marijuana is an
illegal and drug plant

Evidence analysis
-Step1- The Evidence Analysis Question - Specify a question in a
defined area of practice; or state a tentative conclusion or
recommendation that is being considered. Include of the target
specimens involved, the alternatives under consideration, .
Step 2 - Gather and Classify the Evidence
Step 3 - Critically Appraise Each Article
Step 4 - Summarize the Evidence
Step 5 - Write and Grade the Conclusion Statement

11. SANA
Laboratory reports
Are written for several reasons.
One reason is to communicate the
laboratory work to management.
This presents a commonly used
organization for laboratory reports:
-Abstract
-Introduction
- Results and Discussion
-Conclusions
-Appendices

12. SANA
Transportation of botanical evidence
The purpose of this final stage of the investigation and
inquiry in the process of crime scene to pick and transport
and storage appropriate to the type of physical evidence in
order to ensure integrity of the evidence submitted to the
laboratory storage.

13. SANA
Evidence retention and disposition
The evidence must be handled and packaged in a way that
prevents any change from occurring. The evidence must be
properly packaged according to type and properly labeled and
sealed with appropriate initials to maintain chain of custody.
The integrity of evidence is best maintained when it is kept in
its original condition as found at the crime scene. Trace
evidence should not be removed from the objects they’re found
on unless it is impossible to transport the item.

step-wise method for the collection of botanical evidence
1.Find a specimen
2.Use secateurs for a clean cut of the stem
3.Every specimen should be tagged

15. SANA
4.Attach tags securely to each specimen
