SCOTTSDALE, Ariz. (AP) - The accuracy of blood-testing equipment used by Scottsdale police in drunken driving cases is being challenged.
The Arizona Republic reports that hundreds of drunken driving cases from the past four years could be called into question if the legal challenge is successful. The case could also affect the treatment of forensic evidence in Arizona courts.
Eleven felony DUI cases have been consolidated into an ongoing evidentiary hearing in Superior Court. The question is whether a crime lab technician's decision to use old software on a new blood-testing machine in 2009 has affected evidence handled by Scottsdale's crime lab.
Scottsdale police have declined to comment but issued a statement Friday saying the lab has been accredited since 1996 because its practices for maintaining equipment meet or exceed national standards.
