What to Expect When Pulled Over for DWI in Keller & Southlake, Texas

Causation Difficult to Prove In DWI Intoxication Manslaughter Case | Fort Worth DWI Attorneys

One of the key issues in any criminal case is causation. In order to be found guilty of a crime, a defendant’s actions must be found to have been the cause of the criminal act. While causation may seem like a simple thing to prove, causation may depend as much on the actions of the victim as on the actions of the defendant.

Saenz v. State (14th Court of Appeals, August 2015)

FACTS: Monika Saenz was driving her truck around 3:00 a.m. when she struck Jose Torres, Jr., killing him. Blood drawn over an hour after the accident yielded a blood alcohol concentration (BAC) of .172 for Saenz. The autopsy of Torres determined that his BAC was also .172 at the time of the accident and that he had used marijuana and cocaine prior to his death.

Saenz was convicted of intoxication manslaughter and accident involving injury or death. There was no question as to whether Saenz’s truck hit Torres. Saenz’s only defense was concurrent causation: If Torres’ conduct was clearly sufficient to produce the accident that resulted in his death, and Saenz’s conduct was clearly insufficient to produce that result, then Saenz should be acquitted under the theory of concurrent causation.

Saenz pointed to many features of Torres’ conduct that were sufficient to cause the accident. He was walking in the road in dark clothes while intoxicated in the middle of the night; there was no evidence that Saenz’s car ever left the roadway; Torres was walking on the wrong side of the road; and Saenz was not speeding at the time of the accident. Saenz’s position was that her driving while intoxicated was insufficient to cause Torres’ death because even a sober driver would have struck and killed Torres given his conduct.

As part of her concurrent causation defense, Saenz attempted to admit evidence of Torres’ .172 BAC. However, the medical examiner refused to state his opinion that Torres’ .172 BAC would have affected his normal use of physical or mental faculties. As a result, the trial court did not allow admission of the evidence regarding Torres’ BAC.

On appeal, the Texas Fourteenth Court of Appeals questioned why the medical examiner would refuse to concede that a BAC of more than twice the legal limit for driving may have affected Torres’ use of his mental or physical faculties. Furthermore, the Court noted that the standard for public intoxication is that an individual is intoxicated to the degree that he may endanger himself or others. According to the Court, the evidence of Torres’ .172 BAC may have led the jury to conclude that Torres was a danger to himself while walking in the middle of the road in the dark. Further, the Court held, the BAC evidence might have provided a possible explanation to the jury for why Torres failed to move from the roadway when the vehicle appeared.

After finding that the evidence of the victim’s BAC should have been admitted, the Court addressed the question of whether the failure to admit had harmed Saenz’s case. According to the Court, Torres’ BAC evidence was essential Saenz’s defense, and excluding the evidence denied Saenz the opportunity to properly present her concurrent causation defense. Because the Court determined that exclusion of evidence of the victim’s BAC was error that may have contributed to the conviction or punishment, the Court reversed the conviction for intoxication manslaughter and remanded the case for a new trial.

This case illustrates the complexity of the current causation defense, which is used in cases other than criminal cases, particularly property insurance cases. A Fort Worth Criminal Defense Attorney will be familiar with the concurrent causation defense and may be able to obtain an acquittal for his or her client by showing that the criminal act would have occurred even if the defendant had done nothing wrong because the victim’s conduct would have caused it.

Rejecting the "Science" of Retrograde Extrapolation in Texas DWI Cases

Most people are familiar with the blood alcohol concentration (BAC) level for DWI: 0.08.  Most people, however, are not familiar with "retrograde extrapolation" and the role it plays in determining BAC. A Fort Worth Criminal Defense Attorney will understand the importance of retrograde extrapolation in a DWI case as evidenced by a recent decision from the Texas Fourteenth Court of Appeals.

VELIZ v. STATE (14th Court of Appeals, Houston, 2015)

FACTS: Houston Police Officer Joel Quezada arrested Luis Veliz shortly after midnight. Veliz admitted to having two beers to drink. After Officer Quezada obtained a search warrant, Veliz's blood was drawn at 3:32 a.m. Veliz's BAC was .081.

At Veliz's trial, a criminalist from the police crime laboratory testified that, based on the .081 BAC at 3:32 a.m., Veliz's BAC at the time of the stop would have been between 0.095 and 0.124. The jury found Veliz guilty of DWI.

On appeal, Veliz argued the criminalist's testimony regarding his BAC was not admissible. This is where retrograde extrapolation became important.

The issue in a DWI case is the BAC at the time the defendant was driving. The blood sample is often obtained hours after the arrest. The process for estimating a BAC at the time of arrest based on a blood sample drawn later is known as retrograde extrapolation: a BAC at one point in time (3:32 a.m. for Veliz) is used to estimate the BAC at a time in the past (12:05 a.m. for Veliz).

Mata Factors Must Be Proven In Order to Apply Retrograde Extrapolation in Texas DWI Cases

Texas case law allows retrograde extrapolation testimony if the expert witness understands how to apply and how to clearly explain the process. In assessing such testimony, courts consider the time between the offense and the blood test, how many tests are administered and at what intervals, and any characteristics of the individual that were considered, including weight, gender, drinking pattern, tolerance for alcohol, amount of alcohol consumed, type of alcohol consumed, time of the last drink and what food was consumed. These are known as the Mata factors, based on the case in which they were first applied.

The Mata factors are important because different individuals' bodies absorb and eliminate alcohol at different rates. And calculating a BAC retroactively requires knowing whether the individual was in the absorption phase (increasing BAC) or in the elimination phase (declining BAC). While not every factor must be known, Texas case law requires that if only one test is performed some time after the alleged offense, retrograde extrapolation is reliable only if many of the factors are considered.

The Court found the criminalist did not know many of Veliz's relevant characteristics--his drinking pattern, the time of his first or last drink, or whether he had eaten recently. The criminalist testified she did not know the Mata factors for retrograde extrapolation. She also testified--incorrectly--that all she needed to perform a retrograde extrapolation was the time of the stop and the time of the blood draw. Because the criminalist did not understand and could not explain the subtleties of retrograde extrapolation, the court reversed the verdict and remanded for a new trial.

Some people believe refusing a blood test when arrested for DWI is a good strategy because any delay will result in a lower (and unreliable) BAC. However, a Fort Worth Criminal Defense Attorney will advise that a BAC based on blood drawn several hours after the arrest can be used to calculate a BAC at the time of arrest that will be admissible in court if the retrograde extrapolation appropriately considers some or all of the Mata factors.

On the other hand, if an individual is on trial for DWI, his or her Fort Worth Criminal Defense Attorney should carefully question any BAC evidence, particularly if it is based on a blood draw that occurred some time after the arrest. Retrograde extrapolation is not an exact science, and a jury will be allowed to hear testimony only if the extrapolation is appropriately performed and explained.

Legislative Changes to Texas DWI Laws | Fort Worth DWI Defense Attorneys

DWI Update:  Some clients want to see their DWI video.  Some don't.  Some want to take it home and show their friends and some want to dig a deep hole and bury it away forever.  Since the passing of the Michael Morton act, regardless of their clients' wishes, criminal defense lawyers could not provide a copy of the DWI video without first obtaining a court order or prosecutor permission.  This all changes on 9/1/15.

This past legislative session, the Texas legislature passed House Bill 3791 which amends Chapter 2 of the Texas Code of Criminal Procedure by adding the following paragraph:

Art. 2.139. VIDEO RECORDINGS OF ARRESTS FOR INTOXICATION OFFENSES.

A person stopped or arrested on suspicion of an offense under Section 49.04, 49.045, 49.07, or 49.08, Penal Code, is entitled to receive from a law enforcement agency employing the peace officer who made the stop or arrest a copy of any video made by or at the direction of the officer that contains footage of:

(1) the stop;

(2) the arrest;

(3) the conduct of the person stopped during any interaction with the officer, including during the administration of a field sobriety test; or

(4) a procedure in which a specimen of the person's breath or blood is taken.

Now (beginning 9/1/15) DWI defendants are entitled to receive a copy of the DWI video (if they want it).  There is no clarification regarding whether the defense attorney, or the DA may provide the copy, but at a minimum it may come from the police agency.

DWI Caselaw Update | Fort Worth Criminal Defense Lawyers

The Fifth Amendment protection against double jeopardy is often viewed as a guarantee against having to stand trial for an offense if an individual has already been found not guilty in a previous trial. It also applies to situations where a defendant is charged with more than one offense: Is it double jeopardy if a defendant receives multiple punishments for the same transaction for multiple offenses?

Yousef Benson was convicted of two offenses as a result of a 2010 traffic accident that seriously injured another individual--intoxication assault and felony DWI.  The offense of intoxication assault occurs when a person "by accident or mistake . . . while operating a motor vehicle in a public place while intoxicated, by reason of that intoxication causes serious bodily injury to another."  Felony DWI occurs when a person "is intoxicated while operating a motor vehicle in a public place" and the person has been previously been convicted of two DWI offenses.

The appellant argued that the two offenses should be considered the same offense, which would prevent the imposition of multiple punishments. The state argued that the offenses were separate and that multiple punishment was allowed. The principle point of contention was whether the previous conviction requirement for felony DWI is an element of the offense or is a punishment enhancement.

The Court of Criminal Appeals performed an "elements" analysis. The elements analysis looks at the specific elements of each crime. If each crime has the same elements, then a court presumes that the offenses are the same for purposes of double jeopardy. Conversely, if two offenses have different elements, the presumption is that the two offenses are separate. In either case, the presumption can be rebutted by showing that the legislature clearly intended the opposite result.

In Benson, the CCA focused on felony DWI's requirement of two previous convictions. In some cases, such requirements are viewed as creating a separate offense; in other cases, they are considered an enhancement of the level or the punishment for the offense. As Benson acknowledged, the CCA had already held in earlier cases that the required prior convictions for felony DWI constitute an element of the offense, calling them "specific attendant circumstances" that help define the offense. In other words, intoxication assault and felony DWI are presumed to be separate offenses, and a defendant can receive a sentence for each offense.

The CCA then turned to the question of whether there was evidence to rebut the presumption: Did the legislature intend for the two offenses to be treated as one? The court acknowledged that the two offenses are in the same chapter of the criminal code, a factor that supports the same-offense position. But the court looked at the language of the statute and concluded that if the legislature had intended the two offenses to be the same, they would have structured the statutory language differently.

The court also looked at the name of the offenses, pointing out that both offenses have some form of the word "intoxicate" in their names, although used as a modifier in each name rather than as a noun. The court concluded that this factor slightly favored the same-offense position.

The court noted that the two offenses have the same punishment ranges. Although this factor can favor either position, the court concluded that it slightly favored treating the same-offense view.

The court looked at the focus of the offenses and found intoxication assault to be a result-oriented offense (causing serious bodily injury) and felony DWI to be a conduct-oriented (driving while intoxicated) or circumstances-oriented (two prior convictions) offense. Unlike intoxication assault, felony DWI does not even require a victim. This analysis favored treating the offenses as separate.

Finally, the court considered the history of the two offenses and concluded that the various revisions of the criminal code supported the position that the two offenses are separate.

In its final analysis, the court recognized some factors supported Benson's argument (same offense). However, the court considered the factors supporting the state's position (separate offenses) as "more substantial." In the court's view, the evidence did not support the view that the legislature intended one punishment. Therefore, separate punishment for each offense was not a violation of Benson's right to protection from double jeopardy.

Can I be Arrested for DWI for Sleeping in My Car?

One of the requirements for a DWI in Fort Worth is straightforward--the intoxicated individual must be "operating" a vehicle while intoxicated. Any DWI attorney in Fort Worth would tell you that basic requirement. The Texas Court of Criminal Appeals recently considered the question of whether an individual who is passed out in a running, yet stationary, vehicle is "operating" the vehicle for DWI purposes. In Murray v. State, the court answered in the affirmative.

Chad Murray was passed out in his running truck in the early hours of the morning. Deputy James McClanahan observed Murray's truck with its lights on, parked partially on the shoulder of Highway 22 and partially in a driveway near a fireworks stand. Deputy McClanahan observed exhaust coming from the truck but could not see anyone inside. The Deputy approached the truck and saw Murray asleep in the driver's seat. The truck was indeed running. The transmission was in "park," and the radio was on high volume. Deputy McClanahan finally succeeded in waking Murray up and, after Murray's bungled attempts failed, in obtaining Murray's ID. The deputy reported that he immediately smelled alcohol in the truck when Murray opened the window and that Murray appeared very intoxicated. Murray failed a field sobriety test and was charged with DWI.

At trial, Murray was found guilty and sentenced to one year in jail and a $1,000 fine. The jail sentence was suspended, and Murray was placed on two years of community supervision. Murray appealed his conviction to the Seventh Court of Appeals, arguing that there was insufficient evidence at trial to prove that he was actually operating his truck and that he was, therefore, not guilty of DWI. The court of appeals agreed and reversed Murray's conviction, holding that, although it was possible to infer from the circumstances that someone drove Murray's truck to the location where it was found, there was no evidence as to when that occurred or whether the driver was intoxicated at the time. The Prosecuting Attorney appealed to the Court of Criminal Appeals based on the question of whether Murray could have been found guilty of DWI without direct evidence that he was operating a vehicle while intoxicated.

The CCA took exception to the lower court's conclusion, pointing to evidence that the vehicle was running, that Murray was in the driver's seat, that Murray was the only one in the vehicle and that he was the only person in the vicinity. The court also pointed to the fact that there were no alcoholic beverages or containers in the vicinity and that the Deputy's conclusion that Murray was very intoxicated was reasonable; Murray even admitted to the Deputy that he had been drinking. Because Murray was intoxicated, no one else was around, and there was no alcohol in the area, the court found it reasonable for the jury to infer that Murray had driven his truck to the location on Highway 22 and had done so while intoxicated.

Justice Meyers disagreed and in a dissenting opinion argued that allowing Murray's DWI conviction to stand was comparable to convicting someone for possession of marijuana based solely on the individual being high and smelling of marijuana. Justice Meyers believed that being passed out behind the wheel of a running vehicle is not enough to be considered "operating" the vehicle; operation of a vehicle requires some action to enable the use of the vehicle, even something as simple as turning the key in the ignition. For DWI purposes, there must be evidence that the action was taken while the individual was intoxicated. For Justice Meyers, inferring these facts from the evidence presented was a leap too big for a jury to make.

The case is instructive for anyone charged with DWI in Fort Worth. A trial jury will have wide latitude in drawing conclusions regarding whether you were operating the vehicle while intoxicated, even if an officer does not directly observe you doing so. If you find yourself in this predicament, you should consult a DWI attorney in Fort Worth. Do not assume that you will get off on a technicality. Chad Murray didn't.
