This is Hidden Killers Week in review.

I look back at the most prolific stories of the week.

This is Hidden Killers with Tony Brewski.

DNA evidence, specifically unidentified male DNA,

found in Suzanne Morphew's car, an honored bike helmet,

piece of information

surfaced. But before anyone declares victory or reasonable doubt, there's some circumstantial

nuance that we have to unravel here. We're talking today with former FBI special agent

Jennifer Coffendaffer, who has decades of experience cutting through investigative clutter.

It's going to help us understand

exactly what investigators found, why this DNA isn't the smoking gun. Barry's defense would

love it to be, and how something initially alarming like DNA matches to known offenders could

end up meeting next to nothing in the big picture.

Why does this all matter so much?

Because, as Jennifer Coffendaffer will tell us, jurors often latch onto details that sound dramatic on paper, but lose significance under scrutiny.
