The Pennsylvania State Police are deploying a rapid DNA testing program across the commonwealth that will allow for quick analysis of DNA samples outside traditional laboratory settings.
Troopers have put 15 automated genetic analyzers into use, with results potentially available to investigators in as little as 90 minutes.
State police officials said the quick analysis of DNA samples will provide timely and actionable information to help solve cases and improve public safety.
“This program represents significant advancements in our forensic capabilities,” said Col. Christopher Paris, commissioner of the state police, in a statement. “Rapid DNA analysis can expedite the development of investigative leads, assist in suspect identification, and help exclude individuals with greater speed. Aside from investigative efficiency, this technology provides accuracy, fairness, and better outcomes for the communities we serve.”
The technology proved its value during its first week of deployment when troopers investigating an ATM tampering incident obtained a blood sample. The sample was compared to a DNA database, and investigators received a notification identifying a potential lead in under two hours, troopers said.
State police said that they adhere to all state and federal guidelines for DNA collection and privacy protections.
With the rollout of the units, state police will only allow members of the Forensic Service Unit (FSU), who have completed the department’s required training, to operate the analyzers, and laboratory personnel conduct the necessary analysis to verify matches.
The expanded use of DNA testing and rapid DNA by the state police has the support of Democratic Gov. Josh Shapiro, officials said.
As rapid DNA programs become more common in policing, concerns have been raised regarding the acquisition of DNA without a warrant and the retention of samples.
While rapid DNA results are often sufficient to focus investigations, more detailed DNA testing is typically required for prosecutorial evidence in court.
Bucks County initiated a rapid DNA program in 2017 through a partnership between the Bensalem Township police and the Bucks County District Attorney’s Office.
Bucks County Sheriff Fred Harran, who previously led the Bensalem Township Police Department, was instrumental in bringing the technology to the county.
“Having championed and implemented rapid DNA technology during my time in Bensalem Township and brought that emphasis here to the sheriff’s office, I know firsthand the immense power this tool holds in solving crimes and bringing justice to victims,” Harran said. “This statewide rollout by the Pennsylvania State Police is a tremendous stride forward for law enforcement in the Commonwealth and will undoubtedly enhance our collective ability to keep communities safe.”
