Hair comparison evidence

Microscopic hair analysis could not scientifically distinguish one individual to the exclusion of all others.
Statistical weight could not be given to comparisons to suggest a likelihood that the hair derived from a specific source.
Expert witnesses should not cite the number of hair analyses they had conducted in the lab to bolster the idea that they could definitively state that a hair belonged to a specific individual.

All of these factors sways a jurors opinion based on evidence that are not completely true

No physical evidence was found against him; there was no blood, no semen, and no way to trace DNA. There was only one strand of hair that was used to charge Perot with the crime.

The prosecutor's testimony

He discussed that:

head and pubic hairs were distinctive
described the medulla, cortex, and cuticle
that two hairs from different people was unlikely to be alike

The Victim's Description

The victim described her attacker as a man with a short haircut and clean shaven. Perot has shaggy hair and at the time of the incident had a goatee and a mustache

The effect

The argument for one strand of hair was so strong that it made the jury believe there was no other option except for Josh Perot to be the attacker

The Truth?

Even though this "expert analysis" believed his work, his argument was wrong.
