Ballistics Evidence: Trayvon Martin / George Zimmerman Case Study

The shooting of Trayvon Martin by George Zimmerman is an excellent case study where Forensic ballistics evidence was able to push through emotions and opinions. Most of my high school students have never heard of the case, which is great because we get to really discuss the evidence before they find out the verdict!

Description

The shooting of Trayvon Martin by George Zimmerman is an excellent case study where Forensic ballistics evidence was able to push through emotions and opinions. Most of my high school students have never heard of the case, which is great because we get to really discuss the evidence before they find out the verdict!

This resource is best used after students have an understanding of how ballistics evidence works. They will see the testimony of the Forensic Firearms Expert from the actual trial. She will briefly discuss the differences between the bullet and the cartridge case, the firing mechanism of Zimmerman’s gun, how a bullet is linked to a particular gun, and the significance of GSR (gunshot residue) evidence.

The Case:

George Zimmerman was charged with 2nd degree murder for the killing of Trayvon Martin in 2012. Zimmerman claims he acted in self-defense, while Martin’s family (and much of the public) accuse him of racially profiling Martin, who was unarmed and walking home from a convenience store. They claim Zimmerman stalked, attacked, and shot Martin needlessly.

The gunshot residue evidence is the highlight of the trial. The forensic firearms expert demonstrates that GSR patterns on Martin’s sweatshirt are consistent with a contact shot. Students will then hear from the pathologist who did the autopsy. He testifies that the GSR pattern on Martin’s chest is that of ‘intermediate range’ between 2 and 4 inches. What does that mean? You will have to watch and see!

Here are what some Happy Teachers have to say about this Zimmerman Case Study in our Teachers Pay Teachers store:

My students enjoyed this real life case study. The links to the news/court footage was especially intriguing to them and useful for our discussions.           – Lindsay F.             May 5, 2021

Worked very well with online kiddos and in-class kids. I used it as a group activity after we had gone over Ballistic Evidence. The whole class was totally engaged.              – Barbra B.       April 27, 2021

I will be keeping this as an addition to my ballistics unit for years to come!         -Mrs. Jan       March 2, 2022
