A man on a 1st date and 'in the prime of his life' was killed after a Texas woman drunkenly crashed her Porsche onto a city sidewalk at 100 mph, prosecutors say

• A Houston man was killed in late April by a driver going over 100mph in a Porsche.
• The driver lost control of the car and hit a man on a date walking on the sidewalk, killing him.

A Texas socialite accused of drunkenly driving her Porsche faster than 100mph onto a sidewalk, killing a man who was on a first date, has been sued by the man's family after prosecutors separately charged her.

According to a civil lawsuit filed in Houston on April 26, 33-year-old Joseph McMullin was killed by a drunk driver on April 19, while out on a first date at a donut shop in Houston. Kristina Chambers, was charged with intoxication manslaughter by prosecutors on April 21, which was followed by the wrongful death lawsuit brought by the man's parents.

McMullin's family's lawyer Jesus Garcia told Insider McMullin was "loyal" and in "the prime of his life."

Surveillance video from the night of the crash shows Chambers' Porsche speeding onto a curb where McMullin was walking, and striking him, sending him into the air, while Chambers drives away before crashing into a pole, according to KHOU-TV.

Garcia told Insider that the surveillance video of the crash, details around how much Chambers had to drink, and where she drank that night, would be key facts for the case.

"It didn't have to happen, and it was all in the control of Ms. Chambers," Garcia said.

Prosecutors said that Chambers was four times over the state's legal alcohol limit, and had drugs in her system, per KHOU-TV.

Chambers is the wife of a wealthy Houston trader named Xuan Si, according to The New York Post.

Chambers' attorney did not immediately return Insider's request for comment, but has denied the allegations, per The Houston Chronicle.

McMullin's family is seeking at least $1 million in damages on the grounds of negligence and wrongful death, according to their civil lawsuit.
