When prosecutors learned that Minnesota authorities weren't always getting DNA from convicted felons, Ramsey County Attorney John Choi asked the chief of his criminal division, Richard Dusterhoft, to double-check their files.
At first skeptical, Dusterhoft grew alarmed when he discovered that dozens of felons were slipping through the cracks each year, despite a state law that requires samples from them.
"Eighty-five in 2010, that was a big surprise to me, that it was as many as it was," he said.
Whether those felons are in prison, freed or on probation, it's proven a daunting challenge to track down 61 of them, so far, to get the samples they should have given in 2010 -- plus more felons who should have given samples in earlier years, too. With DNA an increasingly important tool for solving crimes, criminal justice officials are calling for more vigilant collection efforts.
"This potentially could solve past crimes and could lead to solving future crimes," said Choi. "That's one reason why we've spent a lot of energy and focus on this -- because we can see the value to the public's safety."
Exhaustive search
Choi decided to have Dusterhoft check the state Bureau of Criminal Apprehension (BCA) Convicted Offender Database after hearing Hennepin County's senior prosecutor, Steve Redding, sound the alarm at a Minnesota county attorneys' meeting in September 2011.
Redding had found that in 2010, out of 3,500 felons convicted in Hennepin County, 125 never had DNA samples, typically collected through a cheek swab, entered into the database.
