Porsche Driver’s Insane Defense for Killing Innocent Man

A Houston woman facing manslaughter charges after killing a man on his first date wants you to believe her Christian Louboutin heels, not her blood alcohol level nearly four times the legal limit, caused the fatal crash.

Story Snapshot

  • Kristina Chambers, 34, drove her Porsche at 70 mph into Joseph McMullin, 33, launching him 30 feet and killing him instantly outside a Houston donut shop at 2 a.m.
  • Her blood alcohol measured 0.301—nearly quadruple Texas’s legal limit—with cocaine found in both her car and purse after the April 2023 crash.
  • Defense attorney Mark Thiessen claims her designer heels stuck on the gas pedal, not intoxication, caused the tragedy on what he calls Houston’s most dangerous curve.
  • Chambers faces second-degree manslaughter charges carrying 2-20 years in prison, plus a $1 million civil lawsuit from McMullin’s grieving family.

When Designer Footwear Becomes a Legal Defense

The audacity of Mark Thiessen’s defense strategy deserves acknowledgment, if only for its creativity. According to the attorney representing Chambers, those sleek Christian Louboutin heels—known more for their red soles than their safety features—somehow wedged against the accelerator at precisely the wrong moment. Never mind the 0.301 blood alcohol content. Ignore the cocaine stashed in her vehicle. Focus instead on the footwear. This argument asks jurors to suspend disbelief in spectacular fashion, essentially claiming that expensive shoes possess more culpability than a driver nearly comatose with intoxication behind the wheel of a luxury sports car.

The Brutal Mathematics of Drunk Driving

Joseph McMullin never had a chance. Exiting a donut shop with his date around 2 a.m. on April 19, 2023, he stepped onto a Houston sidewalk moments before Chambers’ Porsche 911 Carrera mounted the curb at approximately 70 mph. The impact sent his body airborne for 30 feet—roughly the length of three full-sized pickup trucks parked bumper to bumper. His date witnessed the entire horror. Two passengers riding with Chambers required hospitalization. Meanwhile, investigators discovered a blood alcohol level that would render most people unconscious, let alone capable of operating a high-performance vehicle through Houston’s streets at speeds approaching freeway velocity.

The Prosecutorial Case Writes Itself

Texas law establishes 0.08 as the legal limit for blood alcohol content while driving. Chambers registered 0.301—a figure so extreme it suggests she consumed alcohol with singular determination throughout the evening. Prosecutors classify any BAC exceeding 0.15 as an enhanced DWI offense, triggering harsher penalties. Chambers obliterated that threshold by double. Add the cocaine discovered during the post-crash investigation, and you have a defendant whose impairment extended beyond mere alcohol. The physical evidence—skid marks, point of impact, vehicle damage, and witness testimony—constructs a narrative no amount of footwear-focused deflection can reasonably dismantle.

Personal Responsibility Meets Legal Accountability

The McMullin family seeks $1 million in their civil lawsuit against Chambers, a figure that cannot restore their loss but acknowledges the devastating financial and emotional toll of losing a loved one to a preventable tragedy. Their son died on what should have been a pleasant first date, his life extinguished by someone who made multiple catastrophic choices that evening. She chose to drink to extreme intoxication. She chose to possess cocaine. She chose to drive a powerful sports car at dangerous speeds. She chose to endanger her passengers, other motorists, and pedestrians. At some point, personal responsibility must outweigh creative legal maneuvering.

What the Heel Defense Really Represents

Thiessen’s strategy reveals the desperation inherent in defending the indefensible. When forensic evidence overwhelmingly demonstrates guilt, attorneys sometimes pivot to unconventional arguments hoping to introduce reasonable doubt where none logically exists. The dangerous curve argument carries slightly more weight—Houston does feature treacherous roadways—but combining alleged infrastructure failures with footwear malfunctions while simultaneously dismissing nearly lethal intoxication levels insults the intelligence of potential jurors. This defense essentially asks twelve citizens to ignore common sense, scientific evidence, and basic causation principles. It transforms a straightforward DWI manslaughter case into theater, prioritizing spectacle over substance and deflection over accountability in a case where the facts speak with brutal clarity.
