Detroit The Detroit police crime lab was shut down by the city's new mayor and police chief after an outside audit found errors in some evidence used to prosecute cases involving murder and other crimes, officials said Thursday.
Wrongful convictions are a possibility, according to the audit, conducted by the Michigan State Police. Wayne County prosecutor Kym Worthy also noted that some criminals may have gone uncharged because of the lab's shortcomings.
"We have no idea how many people are walking around that have committed crimes that we don't know about," said Worthy, who blamed the problems on human error, as well as a lack of funding, resources and training.
The audit found erroneous or false findings in 10 percent of 200 random cases and subpar quality control compliance at the lab, Worthy said.
