A Texas Department of Public Safety analysist in charge of handling an unknown number of blood samples pertinent to driving while intoxicated (DWI) cases is facing heavy scrutiny after admitting to errors and opposing testimonies. Christopher Youngkin has tested blood samples and acted as an expert witness in several Texas counties, including Collin, Dallas, and Denton. Any number of his findings could potentially be unusable as evidence due to tampering and mistakes.
Credibility Called into Question
Back in 2013, Youngkin was testing multiple blood samples for DWI cases and inadvertently switched two. The result was a woman in Anna being accused of having a blood alcohol concentration (BAC) level double the legal limit when, in reality, she did not have a drink the night of her arrest. To the woman’s luck, the error was caught shortly after and she was not convicted.
A single error could arguably be excusable but a recent questioning by a defense attorney revealed that Youngkin’s mistakes might be widespread. The defense attorney asked about two conflicting testimonies Youngkin had given, one in a Dallas County case and another in a Collin County case. Instead of providing an explanation for the seemingly-fraudulent testimonies, Youngkin chose to invoke his Fifth Amendment rights, which raised eyebrows, to say the least.
Thousands of Case Results May Be Invalid
People convicted of DWIs throughout Texas are looking into their case results to see if Youngkin’s work or testimony was mentioned. If so, it could be indicative of an invalid case result based on evidence that should have been inadmissible due to a lack of confidence in its findings. At the very least, another examination of blood samples must be conducted for there to be justice.
If you have been convicted of a DWI or DUI in Texas within the last few years, you may need to take legal action to retroactively protect your rights from Youngkin’s potential mistakes.
