Forensic Evidence Links Hannah Graham Case to Other Unsolved Murder

Harrington and GrahamCHARLOTTESVILLE, Virginia — Gone but not forgotten.
Morgan Harrington, a 20-year-old Virginia Tech student, disappeared in October 2009. Her remains were found a few months later.
Her death remains a mystery, but it’s back in the news this week because of the arrest of Jesse Matthew — the only known suspect in the disappearance of University of Virginia student Hannah Graham.
Virginia State Police have not said how the two cases are connected, except to say there is a “new forensic link.”

Application of Proteinases for DNA Isolation of Challenged Bone Specimens

Helix4Forensic analysis of DNA from bone can be important when investigating cases involving violent crimes or missing persons. To remove the potential presence of commingled remains and to eliminate contaminants that interfere with forensic DNA analysis, the outer surface of the bone fragment must be cleaned—a labor‐intensive and time‐consuming step. A simpler, more reliable processing method is needed. This study evaluates two methods for processing bone specimens before their DNA is isolated: mechanical sanding and enzymatic trypsin.

Improved Tools for the Robust Analysis of Low Copy Number and Challenged DNA Samples

Blue and black helixLow copy number (LCN) typing is a general technique used for analyzing low-quantity DNA samples. Short tandem repeat (STR) testing on aged and extremely limited samples, such as “touch DNA” samples, has increased over the past decade. Samples with low quantities of template DNA are typically subjected to exaggerated stochastic effects during the polymerase chain reaction (PCR) that impact the reproducibility and reliability of DNA typing results.

Prosecutors Look to New DNA Testing in Twin Cases

DNA TwinsProsecutors in Boston were forced to put a rape suspect on trial three times before jurors were willing to convict him a decade ago. It wasn’t due a lack of evidence, but because the suspect was an identical twin.
Similar cases have popped up elsewhere, illustrating the challenges of prosecuting a twin. Because identical twins come from a single fertilized egg, standard DNA testing has not been able to differentiate between them.
