Forensic DNA Video Series
Welcome to “Forensic DNA”
Join Jarrett Ambeau — Baton Rouge trial attorney, court-qualified expert in forensic DNA interpretation, and holder of a Master of Science in forensic DNA and serology — for a three-part series on what DNA evidence is and why it matters so much in a criminal case. The goal is simple: to make this complex and intimidating evidence understandable for attorneys and defendants, and in turn to support the reasonable, informed use of DNA evidence in the courtroom.
“Forensic DNA” Episode 1 : What is DNA Measurement?
To understand Forensic DNA, you must understand what DNA is.
In this episode, we talk about measurement and the scale of the DNA molecule. Understanding this will help to support the videos that follow.
“Forensic DNA” Episode 2 : Lab Report
Second video of the forensic DNA profiling series, bringing clarity and understanding to this difficult topic. We take a look at the DNA lab report (alleles, genotypes, DNA statistics, DNA kits used, DNA lab protocols and procedures) received in criminal cases and talk about the information contained therein.
How do you interpret the lab report? What do the parts of the report mean? Can you go to court with just the report, or do you need supplemental discovery? Answering all these questions and more…
“Forensic DNA” Episode 3 : Steps in Lab Analysis
Continuing series on forensic DNA profiling analysis, covering the 6 steps of analysis in the DNA lab.
We first cover definitions of a few terms and then take a quick look at the 6 steps of analysis – DNA Extraction, DNA Quantification, DNA Amplification, Electrophoresis, Software data analysis, and human interpretation.
Keeping in mind how to meet the challenge of DNA evidence in the courtroom as an attorney and/or defendant.
Attorney Jarrett Ambeau also offers forensic DNA consulting and expert witness services to defense attorneys nationwide through Ambeau Forensics.
