Catching a Child Abuser in Five Days

Next week, forensic analysts from all over the world will gather in Minneapolis for the 27th  International Symposium on Human Identification (ISHI). So today, we’d like to share one story from a forensics lab that highlights the importance of collaboration, knowledge-sharing and technology development–since that is what ISHI is all about. 

Crimes against children are especially heinous, and it is vitally important that the offenders are removed from the streets as soon as possible. In today’s blog, Sarah Chenoweth from the Anne Arundel County Crime Lab in Maryland describes a sexual assault case that was solved in just five days. Key to this speed were the collaboration between lab staff and state police, and the ability to quickly and reliably amplify DNA profiles from low-DNA samples. Thanks to the efforts of the investigators involved, parents in Maryland, and possibly nationwide, can sleep a little easier.

On Friday, February 5th, the Anne Arundel County Crime Lab was notified of a sex offense involving a 7-year-old victim. With our efficient DNA workflow, including use of the Fusion amplification kit with our 3500 Genetic Analyzer, we were able to identify the perpetrator in only five days. Continue reading

Addressing the Sexual Assault Kit Backlog: Defining the Problem, Creating Solutions

general tweet from USA article

This post was contributed by  guest blogger Tara Luther in the Genetic Identity group at Promega.

The journalists working on this story uncovered more than 70,000 neglected rape kits in an open-records campaign that covered more than 1,000 police agencies. The story notes that “despite its scope, the agency-by-agency count cover[ed] a fraction of the nation’s 18,000 police departments, suggesting the number of untested rape kits reach[ed] into the hundreds of thousands.”

tweet 3The USA Today effort led not only to national reporting but also to many local stories as well.

EndTheBackLog.org is a program sponsored by the Joyful Heart Foundation aimed at getting policy makers and prosecutors to address the large numbers of untested rape kits in the United States. They hope by researching to identify the extent of the backlog and publicizing that research they will begin a dialog at local, state and national levels that will lead to solutions for addressing it. The USA Today story and local stories have grown out of their efforts to call attention to this problem. Continue reading
