The Kirk Zimmerman murder trial is wrapping up in McLean county. The defense rested Wednesday afternoon. It’s been 15 days since testimony began, during which we’ve heard from 60 witnesses.
Today, the defense called their own expert witnesses today in their pursuit to clear Zimmerman in the 2014 murder of his ex-wife Pam. Gunshot residue, or GSR, was once again the hot topic. A positive test for GSR on the gear shift of Kirk Zimmerman’s car is the only physical evidence against him.
Former FBI special agent and Chief of Gunshot Residue in the forensics lab John W. Kilty testified as a GSR expert. He reviewed the state crime lab’s report from the test on Zimmerman’s gear shift in 2014. He says he would accept the test if it revealed one particle, but the lab found 10. Kilty says finding that much is “astounding.” “Ten is a large amount of particles to find in a sample…It’s surprising and begs some inquiry why they didn’t look into it,” Kilty explained.
Kilty said the smooth plastic surface of the gear shift would make it hard for gunshot residue to stick to it.
And with the amount of driving around Zimmerman did after the shooting, Kilty says it’s unlikely that amount could be on the gear shift days after the murder without some sort of contamination.
This afternoon the defense rested *without* calling their own expert witness on cellular technology.
Kilty was the last witness for the defense, ending without testimony from kirk zimmerman.
The state was prepared to recall detective Martin Krylowicz to present a re-creation video that was intended to show Krylowicz process of collecting a gunshot residue sample. The judge ruled the video was inadmissible.
The defense argued that Krylowicz contaminated Zimmerman’s car because no gunshot residue was found anywhere other than the gear shift.
Closing statements begin at 10:00 am Thursday. The prosecution will go first, followed by the defense. The prosecution will then have the opportunity to respond before the jury deliberates.
