The outside investigation of the state crime lab has led North Carolina's attorney general to suspend the six-agent unit that analyzes bloodstain patterns.
Attorney General Roy Cooper says he asked the two former assistant FBI directors investigating the lab to review cases involving blood-spatter analysis. The lab is part of the State Bureau of Investigation, where Cooper named a new director Thursday.
Cooper said Friday that investigators reviewed the cases and agreed that the program should be suspended until issues about the unit have been studied.
The News & Observer of Raleigh first reported the suspension of the unit's work in Friday's editions.
Cooper initiated the outside investigation after a hearing in February showed SBI agents withheld some test results.
