Kingwood, TX: Intoxicated Driver Charged in Fatal Crash that Killed Elderly Couple

Intoxicated Driver Charged After Fatal Kingwood Collision

A 40-year-old man has been charged with intoxication manslaughter following a car crash in Kingwood, Texas, that resulted in the deaths of a husband and wife. The collision occurred on July 13, 2025, at the intersection of West Lake Houston Parkway and Magnolia Cove Drive.

According to reports, the incident happened at approximately 5:45 p.m. An elderly couple, identified as 60-year-old Curtis Van Diest and 66-year-old Catherine Van Diest, were traveling in a white Cadillac XT5 SUV. They were stopped at a stop sign while traveling northbound on Magnolia Cove Drive. As their vehicle pulled out into the intersection, it was struck by a Ram pickup truck.

The force of the collision caused the pickup truck to hit a nearby pole before landing on its side. Paramedics responding to the scene pronounced both Curtis and Catherine Van Diest dead. The driver of the pickup truck, John Nathan Dool, sustained non-life-threatening injuries and was transported to a local hospital.

Following an investigation, authorities determined that Dool was impaired at the time of the crash. He has since been charged with two counts of intoxication manslaughter. The investigation into the collision is ongoing.

Understanding Intoxication Manslaughter in Texas

Intoxication manslaughter is a serious offense in Texas, defined as causing the death of another person while operating a motor vehicle in a state of intoxication. Intoxication, in this context, means having a blood alcohol concentration (BAC) of 0.08% or more, or not having the normal use of one’s mental or physical faculties due to the introduction of alcohol, a controlled substance, a drug, or a combination of these substances.

In Texas, intoxication manslaughter is classified as a second-degree felony. A conviction for this offense carries a potential prison sentence of between two and 20 years, as well as a fine of up to $10,000. Beyond the criminal penalties, individuals convicted of intoxication manslaughter face a host of other consequences, including a permanent criminal record, difficulty securing employment, and the loss of their driving privileges.

Civil Liability in Intoxication-Related Accidents

In addition to criminal charges, an intoxicated driver who causes a crash may also face civil liability. This means that the victims of the crash, or their families, can pursue a personal injury lawsuit against the driver to recover compensation for their losses. These losses can include medical expenses, funeral costs, lost wages, pain and suffering, and other damages.

Unlike criminal cases, which are brought by the state, civil lawsuits are filed by the injured party. The burden of proof is also different in civil cases. While a criminal conviction requires proof beyond a reasonable doubt, a civil case only requires a preponderance of the evidence, meaning it is more likely than not that the defendant’s actions caused the injuries.

The Importance of Legal Representation in Wrongful Death Cases

The aftermath of a fatal car accident can be an incredibly challenging time for the surviving family members. In addition to grieving the loss of their loved ones, they may also be faced with financial burdens, such as funeral expenses and lost income. Pursuing a wrongful death claim against the responsible party can help alleviate some of these financial pressures.

A wrongful death claim is a type of personal injury lawsuit that is brought on behalf of the deceased person’s family. In Texas, certain family members, such as the surviving spouse, children, and parents, may be eligible to file a wrongful death lawsuit. These claims seek to recover compensation for the losses suffered by the family as a result of the death, which can include:

  •   Funeral and burial expenses
  •   Medical bills incurred prior to death
  •   Lost wages and future earning capacity of the deceased
  •   Loss of companionship and emotional support
  •   Pain and suffering

Navigating the legal process after a fatal car accident can be complex and emotionally draining. It is important for families to seek the guidance of a seasoned personal injury attorney who can help them understand their rights and options. An attorney can investigate the circumstances of the crash, gather evidence to support their claim, negotiate with insurance companies, and, if necessary, pursue litigation in court.

Factors Contributing to Intoxication-Related Accidents

Intoxication-related car accidents are a persistent problem across the United States. A number of factors can contribute to these incidents, including:

  •   Impaired Judgment: Alcohol and drugs can impair a person’s judgment, making them more likely to take risks, such as speeding or driving aggressively.
  •   Slower Reaction Times: Intoxicating substances can slow down a person’s reaction time, making it difficult to respond quickly to changing traffic conditions.
  •   Reduced Coordination: Alcohol and drugs can also affect a person’s coordination, making it harder to control a vehicle.
  •   Overconfidence: Some individuals may feel overconfident in their driving abilities while intoxicated, leading them to make poor decisions.
  •   Social Influences: Peer pressure and social norms can sometimes encourage people to drive after drinking or using drugs.

Preventing Intoxication-Related Accidents

Preventing intoxication-related accidents requires a multi-faceted approach involving individuals, communities, and law enforcement. Some key strategies include:

  •   Designated Drivers: Designating a sober driver is one of the most effective ways to prevent drunk driving.
  •   Ride-Sharing Services: Utilizing ride-sharing services like Uber and Lyft can provide a safe alternative to driving while impaired.
  •   Public Transportation: Taking public transportation, such as buses or trains, can also help prevent drunk driving.
  •   Responsible Alcohol Service: Bars and restaurants have a responsibility to avoid over-serving patrons and to prevent intoxicated individuals from driving.
  •   Education and Awareness Campaigns: Public awareness campaigns can help educate people about the dangers of drunk driving and the consequences of impaired driving.
  •   Strict Law Enforcement: Law enforcement agencies play a crucial role in deterring drunk driving through increased patrols, sobriety checkpoints, and strict enforcement of DUI laws.
