Innocence Project Requests Investigation of Baltimore Crime Lab

By TChris

Speaking of police crime labs that produce unreliable results, the Innocence Project recently asked the Maryland state police to investigate the Baltimore police crime lab.

The Innocence Project, a national group of lawyers who try to exonerate convicts based largely on new DNA evidence, wrote in the complaint that "serious negligence or misconduct substantially affecting the integrity of forensic results has occurred at the Baltimore Police Department Crime Laboratory... Recently, the BPD-CL revealed that a lab employee working in the DNA lab contaminated evidence in approximately 12 open cases."

Lab staff didn't wear gloves when handling evidence, and the lab failed to enter the DNA profiles of its staff members into its database, causing staff contaminations to appear as "unknowns." These were among the failures of management that caused the crime lab's director to be canned in August. [more...]

[T]he Innocence Project alleged the contamination "can incorrectly steer investigators away from identifying criminals, can weaken criminal prosecutions [by suggesting that another, unidentified person's DNA was present at the crime scene], and can lead police to discount what should be strong DNA evidence and instead focus on innocent suspects."

As to whether the state police will accept the invitation to investigate the crime lab: a spokesperson says they're "carefully considering" the complaint but can't say when they might respond.
