Doubt in the Darlie Routier case: The subjective science (part 1)
September 3, 2012
The prosecution’s case against Darlie Routier, presented in court in 1997, was based on circumstantial evidence. Lacking true and convincing physical evidence directly linking Darlie to the murders of her two sons as well as the attack inflicted on herself, the prosecution focused on an approach to crime scene analysis that the National Academy of Sciences has stated is “more subjective than scientific”. That approach is known as bloodstain pattern analysis.
In 2010, the Texas Observer pointed out that three confirmed wrongful convictions had resulted from “flawed blood-spatter evidence”. This says nothing about how many wrongful convictions have taken place as a result of subjective bloodstain pattern analysis that have not yet been confirmed, or have not received the kind of attention that some cases do.
Along with the above information, the Observer published a detailed account of the conviction of Warren Horinek. Horinek was a less than sympathetic individual who was indicted by a grand jury on suspicion he murdered his wife, Bonnie. He claimed his wife committed suicide in the family home on March 14th of 1995, after the two had become severely intoxicated during an earlier night out.
An investigation into the alleged suicide resulted in a shared conclusion on the part of the police sergeant responsible for supervising the investigation, the medical examiner who performed the autopsy, the crime scene investigator, and the local district attorney: Horinek’s wife committed suicide using a firearm.
Fort Worth district attorney, Mike Parrish, declined to bring charges against Horinek. He later told the media, “I always thought that it was a suicide…still do.”
Bonnie’s parents did not accept their daughter had taken her own life. Despite a history of depression in the past, they did not believe she was distraught enough during the time period surrounding her death to do something that extreme. Moreover, Horinek has a history of being both obnoxious and sometimes violent when he had too much to drink.
When the district attorney refused to bring charges against Horinek, Bonnie’s parents hired a lawyer who found a way to pursue charges without the assistance of the district attorney. Texas law allows any individual to bring evidence in front of a grand jury to seek an indictment. It is a well known fact that when a grand jury is presented with evidence, it is easy to get an indictment. This case was no exception.
However, the district attorney continued to refuse to prosecute Horinek. He claimed he had an ethical duty to refrain from charging a person with a crime when he believed that person was innocent. As a result, the district attorney’s office in Tarrant County assigned two attorneys working in private practice to fill in as special prosecutors. These attorneys had access to resources the district attorney’s office would not otherwise have had.
Everything was backwards at Horinek’s trial. The people who ordinarily testify on behalf of the prosecution testified on behalf of Horinek’s defense. This included, but was not limited to the sergeant in charge of the investigation, the district attorney who refused to seek charges in the first place, and the crime scene investigator. It was a situation that should only exist within an episode of the Twilight Zone.
For the majority of Horinek’s trial it appeared that he would be acquitted. Even the foreman of the jury would later reveal that an acquittal was imminent.
That is, until Tom Bevel took the stand.
Before Tom Bevel ever testified at Darlie Routier’s trial, he testified at what may only be described as the “bizarre” trial of Warren Horinek. Though bloodstain pattern analysis has been used since the late 1800s, it was and still is rarely used as the primary evidence against a defendant. It is often used to strengthen a case that is already based on physical evidence, such as DNA or fingerprints.
In 1996, when Bevel took the stand to testify that Horinek murdered his wife and that this contention could be confirmed through bloodstain pattern analysis, the National Academy of Sciences was 13 years away from publishing a report that outlined the serious limitations of using this approach to crime scene analysis. The jurors who listened to Bevel found his testimony credible and convincing.
Bevel stated that tiny bloodstains on the shirt Horinek was wearing on the evening of his wife’s death could only have resulted from a “high velocity occurrence”. He claimed the cause of the bloodstains was Horinek’s use of a gun. He argued that Horinek’s repeated attempts to administer CPR were not the cause.
The jury subsequently changed their mind about Horinek’s innocence and convicted him of murdering his wife. They did this based on Tom Bevel’s testimony.
The Observer wrote, “Most criminal justice experts believe that flawed forensic evidence – and overreaching expert witnesses – have sent thousands of Americans to prison for crimes they didn’t commit”. The article went on to state that a number of commonly used sciences presented in United States courtrooms, including bloodstain pattern analysis and arson investigations, are really just “junk sciences”.
Jim Varnon was one of the officers who responded to the scene. He believes that Horinek was wrongfully convicted and has put together extensive evidence countering the bloodstain pattern analysis presented by Bevel. He has been fighting to prove Horinek’s innocence ever since.
Horinek has since tried to appeal his conviction. In late 2011, the Observer provided an update on his case, explaining that there were two hearings in 2011 that occurred in reference to his case. Three forensic experts “testified that overwhelming evidence points to a suicide”.
However, despite this and the fact that Bevel has been involved in other suspected wrongful convictions, including one in which a convicted man was later exonerated, Horinek remains imprisoned in Texas.
There are similarities in the case of Warren Horinek and Darlie Routier. Both cases were based on circumstantial evidence. Both prosecutors presented Tom Bevel’s “expert” testimony regarding bloodstain analysis. Both crime scenes contained evidence that supported the convicted person’s version of the events – claims that Bevel used a science that has substantial limitations to discredit.
The very group that claims Tom Bevel as a charter member known as the Scientific Working Group on Bloodstain Pattern Analysis (SWGSTAIN), “recognizes that the opinions of bloodstain pattern analysts may contain an element of subjectivity”.
Really? In light of this information, one has to ask just how reliable a conviction is when the weight of the prosecution’s case rests on this type of “science”. One also has to wonder just how many people convicted based on this science are truly innocent.
In the next article I will describe the case in which Bevel’s testimony helped to send a juvenile to prison for life, without the possibility of parole. This same teenager grew into a man behind bars, but was exonerated based on an advanced approach to DNA testing.
