DNA Typing: Useful Tool to Solve Crimes or Invasion of Privacy?

DNA in a test tubeThis year marks the tenth anniversary of the complete human genome sequence. The Human Genome Project revealed a surprising fact: Only 1% of our genome encodes proteins. This equates to a paltry 20,000–25,000 genes. The function of the other 99% of our DNA remained a mystery. Shortly after the sequencing was completed, the National Human Genome Research Institute (NHGRI) launched a new research project, termed the Encyclopedia Of DNA Elements (ENCODE), to identify DNA elements and try to find a purpose for the other 99% of our DNA. This project has contributed greatly to our understanding of the human genome, as documented in the 30 ENCODE-related papers published in Nature, Genome Research and Genome Biology in 2012 (see the Nature web site. However, the ENCODE project is being used in an unforeseen way: to support an appeal to the recent US Supreme Court decision about the constitutionality of collection and analysis of DNA from arrestees.

Identifying the Victims of John Wayne Gacy

John Wayne Gacy was a notorious serial killer who sexually assaulted and murdered 33 boys and young men in the 1970s in Chicago, Illinois. The killing spree stopped only when he was arrested in 1978 after the parents of his last victim contacted police with critical information that implicated Gacy in the boy’s disappearance. He was tried, convicted and in 1994 executed for his crimes. Of the 33 victims that police found buried in and around his home, only 25 could be identified, leaving eight victims nameless and eight families to wonder if their missing loved one died at the hands of this evil man. When all available means of identification were exhausted, these eight sets of remains were buried but not forgotten.

In 2011, these remains were exhumed and the victim’s DNA analyzed to try to provide clues as to their identity. Continue reading “Identifying the Victims of John Wayne Gacy”

Join the Fun! Learn About Cutting-Edge Forensic Science. Attend ISHI.

International Symposium on Human Identification logo
Join me in Washington, D.C., for the 22nd ISHI.
Well, I just booked my plane tickets to Washington, DC., to attend the 22nd International Symposium on Human Identification (ISHI), which is being held October 3–6. I am excited because every year ISHI is filled with great presentations and posters that represent the newest advances in forensic science. Plus, I have opportunities to interact with some of the greatest minds in the field. These opportunities include more formal interactions, such as asking questions of presenters during the general session and poster sessions and “talking shop” during the breaks, lunches and evening events, but also informal interactions like chatting between mouthfuls of Texas barbecue (16th and 21st ISHI), line dancing (17th ISHI in Nashville, Tennessee), sipping Pinot Noir at a Hollywood hotspot (18th and 19th ISHI) and having pictures taken with a fairly convincing Elvis impersonator (20th ISHI in Las Vegas, Nevada).

What are the hot topics that will have attendees buzzing this year?
