Introduction

The O.J. Simpson trial was one of the most publicized cases of the 20th century. Charged with killing his ex-wife, Nicole Brown, and her friend, Ronald Goldman, Simpson was acquitted of all charges although his DNA was found at the crime scene and on evidence. 

Investigators and police were accused of mishandling and planting evidence, which led to the jury finding Simpson not guilty.

In this lesson, you will read about more cases involving DNA. You will research a case of your choice and also discuss your thoughts on DNA used as evidence.
