Presentation: Forensic DNA
Presenter: Chief Deputy District Attorney John Kellner

The presentation will focus on Forensic DNA in the courtroom from a prosecutor’s perspective and how it has been used it to achieve murder convictions in a variety of cold cases. John Kellner will provide an overview of the common sources of DNA, including some surprising items that prosecutors have been able to pull DNA from in real life. The presentation will cover some different types of DNA analysis including mitochondrial, YSTR, and familial, with real-life examples of how it helped solve crimes or gain convictions.He will also discuss a cold case murder from 1994 in Boulder and the subsequent trial of Michael Clark in 2012, and the 2015 trial of Jon David Harrington for the murder of Carolyn Jansen in 2002. Finally, he will discuss some recent advances in DNA analysis such as rapid DNA testing for use in the field, and phenotyping to generate a composite sketch of a suspect.

John Kellner is a Chief Deputy District Attorney in the Eighteenth Judicial District Attorney’s Office, the largest and most populated jurisdiction in the state of Colorado.

In 2016, John was recognized as the Prosecutor of the Year for the entire state by the Colorado District Attorney’s Council.
