Texas has a mish-mash of regional crime labs which cross pollinate into counties without a dedicated facility. Some are accredited by the ASCLD. Here is its’ police and commercial lab corporation’s approved list of Texas labs. I don’t see Collins County present.
This report of lab misconduct puts the onus on this “top” serology/tox examiners’s employer whom ever that may be.
“One the state’s top forensic experts responsible for blood testing in several DWI cases is under scrutiny for mixing up lab tests. He’s also accused of making conflicting statements under oath.
The swirling allegations of possible perjury stem from a current DWI case in Collin County. A hearing this week could affect many other DWI cases in seven counties since 2013.”
At one point in the public proceedings the judge told this person to stop talking.
