A Texas woman’s defense in a fatal drunk driving incident has taken an unexpected turn as she claims her designer footwear was the cause of the crash.

Kristina Chambers, 34, faces manslaughter charges following the death of 33-year-old Joseph McMullin in April 2023, as reported by the New York Post.

Prosecutors argue that Chambers had been bar-hopping with friends and was significantly over the legal alcohol limit, which led to her hitting McMullin as he exited a Voodoo Doughnut shop in Houston with his date. According to the Houston Chronicle, authorities also discovered small amounts of cocaine in her vehicle and handbag.

At the start of Chambers’ trial on Friday, her lawyer, Mark Thiessen, introduced a different perspective on the tragic event.

Thiessen reportedly argued that Chambers’ high-end Christian Louboutin heels became wedged on the gas pedal of her blue Porsche as she navigated “one of Houston’s most dangerous curves,” the Post reported. 

During Chambers’ trial, prosecutor Andrew Figliuzzi hit back against the defense team’s claims, telling the jury that Chambers was “itching to show off her sports car” to her friends as she was driving the night of the wreck, according to the Post.

Briana Iturrino, who was on a date with McMullin when Chambers’ vehicle allegedly plowed into him, told the jury they had just left the restaurant at around 2:25 a.m. when she noticed headlights heading straight toward them. 

Iturrino reportedly testified that Chambers’ Porsche — estimated to have been traveling over 70 mph — sped past the couple, just barely missing her. As she spun around to warn McMullin of the oncoming vehicle, she realized he was gone. 

“I thought he had gotten out of the way,” Iturrino said, according to the Post. “Because I couldn’t find him.”

Iturrino added that she felt something touch her hip as the car sped past, later realizing it was McMullin being thrown 30 feet in the air as Chambers’ Porsche slammed into a pole. She then reportedly placed a 911 call and proceeded to perform CPR on McMullin until paramedics arrived. 

McMullin was pronounced dead at the crash site. 

Alfredo Ponce, the general manager of a nearby pool hall, testified that he heard the crash and ran outside to help, adding that it was one of the worst wrecks he had seen, according to the Houston Chronicle. 

“I’ve seen so many accidents on that road,” Ponce said. “Every time, I get out and help whoever needs help and is injured.” 

During his testimony, Ponce told the jury he remembered Chambers’ vehicle smelling of alcohol as he attempted to help the injured driver and two passengers, the Houston Chronicle reported. 

Chambers has pleaded not guilty to manslaughter charges.

In addition to her criminal charges, Chambers also faces a $1 million wrongful death lawsuit filed by McMullin’s family, according to the Post. 

The lawsuit reportedly places partial blame on Chambers’ ex-husband, hedge fund manager Xuan Si, for purchasing the high-end sports car in the months leading up to the fatal wreck. Si filed for divorce from Chambers after she was released on bail, the Post reported. 

Despite the allegations, Si reportedly claimed his ex-wife used cash from the couple’s joint account to make the purchase, insisting Chambers did not have a drinking problem and that he had never seen her take drugs or drive drunk. 

Si did not immediately respond to Fox News Digital’s request for comment. 

However, Sebastian Lopez, a friend of Chambers who was inside the car on the night of the crash, said in a deposition she could be described as an “alcoholic,” while alleging Si was aware of her regular use of alcohol and drugs, according to the Post. 

Lopez also reportedly added that Chambers had previously driven drunk “a handful” of times. 

While Chambers’ criminal trial is ongoing, the lawsuit filed against her will be heard by a judge in April 2026. 

Chambers’ attorney and the Harris County District Attorney’s Office did not immediately respond to Fox News Digital’s request for comment.
