In May, police in Falls Township, Bucks County, pulled over Corey Sean Mcgrogan after getting a call about an intoxicated driver. Three months later, he's still waiting for a district judge to review his case and decide if it should go to trial. The delay is the result of a backlog at Bucks County's crime lab for tests that identify illegal substances.

Validation of Highly-specific Protein Markers for Identification of Biological Stains

Although DNA analysis of an evidentiary swab may reveal the presence of a DNA profile consistent with an alleged victim, the DNA profile cannot indicate whether the DNA came from saliva, vaginal fluid, urine, or a host of other sources. The ability to confidently associate a DNA extract with a specific tissue source or to accurately characterize mixed stains, however, can provide criminal investigators with critical information.

Human mitochondrial DNA (mtDNA) analysis, in a forensic setting, is currently limited in breadth (the quantity of sequence data obtained) and depth (the ability to detect minor variants arising from mutations but present at very low levels). The goal of this research was to generate information on the whole mtDNA genome sequence from limited DNA samples, which would greatly expand the potential uses of this marker system.
