This is the Hidden Killers podcast with Tony Bruske and continuing coverage of the case against Karen Reid.

DNA is usually a pretty big thing in a murder case.

Here, I'm wondering how strong a role it's playing.

I mean, they did find DNA on Karen Reid's rear bumper in the form of a hair of John O'Keefe,

or they found it out where the taillight was cracked.

connecting John O'Keefe directly to the accident with Karen's car?

where, you know, normal people, jurors have watched CSI Law and Order. They get wind of these

forensic analyses that are conducted, including DNA and how important they can be and what they

can show. And so here, you know, in terms of a vehicle strike, you've got the guy's DNA on the

back of the vehicle where prosecution is saying it struck him.

I think that's pretty darn strong. Defense might argue in closing, hey, they were dating at the time

and he had other contact with the car. But, you know, with that part of the car on the back of the

O'Keefe had 36 abrasions on his arm, no broken bones.

Prosecution says it's consistent with being struck and dragged along broken
