Plants have long been used as both weapons and evidence in criminal in
vestigations. The proceedings of Socrates' trial and subsequent adjudi
cated suicide by means of Conium brew are in the botanical folklore. I
n this country, plants as poisoning agents have always been well known
, but only since the Lindbergh kidnapping trial have other kinds of bo
tanical evidence gained legal sanction. Botanical resources for forens
ic evidence remain underutilized because of the lack of botanical know
ledge among most people involved in criminal investigations. However,
resourceful investigators and scientists with initiative are beginning
to change this. Now, evidence from plant systematics, palynology, pla
nt anatomy, plant ecology, and related fields is acceptable. The movin
g forces behind increasing the uses of non-traditional scientific fiel
ds in criminal investigations continue to be innovative criminal inves
tigators and imaginative scientists willing to contribute their talent
s to forensic efforts.
