I'm back at the Lee County Justice Center where the
#SieversTrial has resumed after a few days off for the holiday.
The prosecution has called it's first witness of the day. It's Linda Otterstatter, of the FBI’s trace evidence unit.
Otterstatter defines trace evidence for the jury. Trace evidence is small in size, such as hairs, fibers or soil, and can be transferred between two people or a person and an object.
Otterstatter explained to the jury how fibers are examined. Matching fibers is a process of elimination. Trace evidence is collected via picking, scraping, taping or vacuuming, Otterstatter said.
Once the trace evidence is collected, it is examined on glass slides underneath a microscope, Otterstatter said.
Trace evidence is examined to determine if it is a fiber or a hair. If it's a fiber, it is examined to determine if it is a natural fiber or man-made, Otterstatter said. Fibers are examined for many characteristics, such as color, shape and size, Otterstatter said.
Otterstatter is talking about fiber comparison microscopy. This technique is used for direct, side-by-side comparison, Otterstatter said.
Evidence recovered from the leg of Teresa Sievers matched fibers taken from a blue jumpsuit recovered in Missouri not far from the home of suspect Jimmy Ray Rodgers, Otterstatter testified last month in the Rodgers trial. I expect the court will hear about this shortly.
