Whodunit?

Technicians evaluate blood spatter,

Other carnage, and lots of brain matter.

Viewing burst glass for clues of its shatter,

Fibers, hairs, other items may scatter.

Arcs and whorls are present in fingerprints,

Shoe size and type can be gleaned from footprints.

Tool marks on surfaces leave some imprints,

With skill, an abundance of helpful hints.

A popular field involves ballistics,

Probing guns’ unique characteristics.

How procedures work involves logistics,

Everything detailed with good statistics.

We shouldn’t forget toxicology,

Or icky bugs with entomology.

Quite complex from their terminology,

But helpful in proving chronology.

A critical actor—the detective,

Who constructs the case from his perspective.

Investigating should be objective,

Ensuring evidence is effective.

Protect the scene and don’t contaminate,

Organic fluids may disintegrate.

New leads produce data which to update,

And suspects for courts to adjudicate.
