Law enforcement officials say they placed such a high priority on catching a man believed to have sexually assaulted four women over three weeks in Detroit that they put 10 percent of the state police's DNA scientists on the case.
The effort paid off with Saturday's arrest of a 39-year-old Detroit resident.
Authorities tell the Detroit Free Press five of the state police's 52 DNA scientists worked for six days to conduct the tests that led to the arrest.
Two serologists analyzed bodily fluids recovered from a sex-assault victim. Two DNA scientists reviewed genetic markers from that sample. And a fifth scientist compared those markers with a federal database of known criminals.
The Wayne County prosecutor's office is considering whether to file charges against the man.
