One of the national organizations that governs DNA laboratories has
ordered the District’s new crime lab to immediately suspend all DNA case
work after concluding that the lab’s procedures are “insufficient and
inadequate.” D.C. Mayor
Muriel E. Bowser ordered the audit by
the ANSI-ASQ National Accreditation Board last month after the U.S.
Attorney’s Office said it had discovered errors in some of the lab’s DNA
analyses. The audit, which was published Friday, criticized the lab’s
practices and said they were not in compliance with FBI standards. It
ordered “at a minimum” the revalidation of test procedures, new
interpretation guidelines for DNA mixture cases, additional training and
competency testing of staff. The DNA analysts at the District’s
Department of Forensic Sciences, according to the audit, “were not
competent and were using inadequate procedures.” The authors of the
review gave the lab a minimum of 30 days to address their concerns. Legal
experts say the audit could trigger a further investigation of hundreds
of District criminal cases — including murder, sexual assault and gun
possession cases — that have involved evidence tested at the lab since
it opened in 2012. In March, The Washington Post first reported
about alleged problems prosecutors said they found in some of the DNA
analysis the lab performed. As a result, the city ordered an
investigation of the lab’s practices.The
city-ordered audit was delivered the same week as the separate audit
ordered by the U.S. attorney’s office. Forensic experts, commissioned by
the attorney’s office, found similar problems.
