With a few quick clicks, Mark Szczepanski uploads the file from his desktop to a simple, red-and-white web page. A few seconds later, a bar graphic turns green.
If Szczepanski was a police officer, he might have just found a rape suspect.
He was using a test version of a new cloud-based DNA database offered by Utah’s Sorenson Forensics, a DNA testing company. Simple to use and easy to update, the LEAD (Local Entry Accessible DNA) Database was created for local police departments and almost instantly compares DNA test results — say, a suspect’s cheek swab with a semen sample collected at a rape scene.
It has the potential to change the way police use DNA testing, allowing them to access the information more easily and use the technology to investigate more crimes, said Lars Mouritsen, Sorenson Forensics’ chief scientific officer.
"It’s pretty simple…but incredibly powerful," he said. The product offers a possible solution to state agencies’ struggle to keep up with the explosive growth of DNA testing in police work, but concerns privacy advocates who question the security of cloud-based computing and the wisdom of entrusting such sensitive information to a private company.
"How are you ensuring that data would be kept safe?" said Marina Lowe, the legislative counsel for the Salt Lake City chapter of the American Civil Liberties Union.
Explosion of DNA data » Since the firstDNA-based conviction in 1987, the technology has become an essential tool for police all over the country. Scientists can now extract DNA from miniscule collections of cells — even a touch can leave enough evidence.
"DNA, for us, is extremely valuable," said Salt Lake City Police Detective Mike Hamideh, a 17-year veteran who spent eight years in homicide and narcotics. And juries schooled on the long-running hit TV show "CSI" are often looking for such scientific, non-subjective data.
"It’s become a standard that investigators are using. The courts are asking for it," Hamideh said.
As the technology allows more DNA collection, laws are also changing to allow investigators to collect samples from more people. In Utah, a state-run database stores DNA information from those convicted of a class A misdemeanor or worse, as well as people arrested for a violent felony with probable cause, said Jay Henry, director of the Utah Department of Public Safety Crime Lab.
"We’ve got probably almost 85,000 samples in the database," Henry said. The more information a database contains, the more valuable it becomes for police. "What we’re seeing is an exponential growth of hits and a real value of these databases to solve crime."
But entering offender information into the database still takes at least a month, and can be as long as six months, Henry said, depending on how much grant money the lab has available.
"If we have the money, we’ve got the information in the hopper. If not, we get the money in the next grant cycle," he said.
Quicker results, faster leads »Sorenson Forensics says their DNA database can help reduce the turnaround time. Instead of relying on state crime labs entering the information into the database, each law enforcement agency could have one or two people authorized to upload profiles, speeding up the process for entering profiles and executing searches.
"There’s been a lot of interest because there’s a real need," Mouritsen said. Police departments could also use DNA testing in more types of crimes.
"It’s sort of up to the agency to decide what goes into the database," Mouritsen said.
The databank doesn’t address the cost of DNA testing, which is a large part of the reason police use the technology primarily in crimes like homicide and sexual assault. Each test still costs hundreds of dollars.
"Just to take a DNA sample from a car prowl, that’s a significant expense," Hamideh said. "We have to be judicial in the way we use tax money."
Still, Sorenson Forensics hopes that as technology advances and the cost comes down, organizing the data into a form usable by people who don’t have years of scientific training will become more important. The price of the service depends on the size of the department, but for a mid-size agency like Salt Lake City, the initial set up would probably be about $10,000, plus about 15 percent of that amount each year for maintenance. No agencies have signed up yet since the product was introduced this month.Next Page >
