AUSTIN (KXAN/AP) - A second complaint has been filed this year against the Austin Police Department's crime lab.
The Austin American-Statesman reports the latest complaint relates to two pending criminal cases from two years ago.
The first complaint this year was against the department's DNA crime lab.
The complaint -- this time against the drug chemistry crime lab -- was filed with the state Forensic Science Commission. A commission committee will likely decide in March whether to recommend further investigation.
The complaint was made by an independent lab in Euless, near Dallas. Officials said it's unusual for one lab to formally complain about another's work.
Crime lab forensic manager Bill Gibbens declined to discuss details because the cases were ongoing.
Austin Police's crime lab was investigated by the FBI and state authorities after allegations of errors by a former analyst. An FBI audit would eventually find no deficiencies in the lab's work.
Earlier this year, former APD forensic scientist Debra Stephens warned District Attorney Rosemary Lehmberg that there is a rush to report results of forensic tests ordered by Austin police -- according to a letter obtained by KXAN News.
Stephens also alleges that evidence has been compromised and could end up in false convictions.
Lehmberg's office sent an email to all Austin defense attorneys alerting them to the allegations that could affect their clients.
Department of Public Safety officials said that "appropriate chemical analysis was performed" on the three examples that Stephens submitted. In her whistleblower letter, however, Stephens said "hundreds" of cases could be at risk.
In the meantime, DPS officials are reviewing several allegations against the crime lab.
