The family of a Texas man, who was killed by a drunken driver while he was on a first date last month, has filed a civil lawsuit against the defendant and is seeking $1 million in damages.

Kristina Chambers, 32, is charged with intoxication manslaughter after she allegedly drunk-drove her Porsche down Westheimer Road in Houston at 100 mph on April 19, plowing into 33-year-old Joseph McMullin, who was walking on the sidewalk with his date.

"Our hearts are with the family of this wonderful young man who was senselessly struck down in the prime of his life," the family's attorney, Jesus Garcia of Khekher Garcia, LLP, said in a Wednesday statement. " Joseph McMullin was a cherished son, loving brother, proud uncle, and the most loyal friend. Joseph’s death was a needless tragedy caused by the reckless and illegal actions of a motorist who showed no regard for the safety of others. "

Garcia added that the McMullin family's attorneys "will do whatever is necessary to hold Ms. Chambers accountable for her actions and furthermore deter others from exercising such indifference and disregard for others’ lives."

McMullin was on a first date at the time of the crash and was walking to a donut shop when Chambers' Porsche 911 Carrera came out of nowhere and headed straight for the couple, according to the lawsuit filed in Harris County.

Chambers' blood alcohol level was nearly four times the legal limit, and authorities found drugs, including cocaine, in her vehicle, according to the complaint.

Her attorney, Mark Thiessen, argues that the state has yet to share proof that his client was driving 100 mph and that "hospital blood is 100% falsely elevated for ethanol." Additionally, Harris County District Attorney, Thiessen said, has not filed any drug charges against Chambers.

"All we've said from the beginning is: We want to properly investigate this case. We want to make sure this was a crime and not just an accident," Thiessen said. "Not every accident is a crime. Every crime is a tragedy, but not every tragedy is a crime."

Thiessen added that the DA's claims are "reckless," and "readers are trying to convict [Chambers] based on sheer emotion, but we haven't really discovered any of the facts yet."

Surveillance cameras apparently captured the crash that killed McMullin, according to the family's attorneys.

Chambers reportedly appeared in court last week in a wheelchair with a sling over her arm, according to KHOU.

McMullin's date, Briana Iturrino, told FOX 26 Houston that she is "in shock that he's gone."

"I was there and saw it happened," Iturrino told the outlet. "Even before I could act on it, I felt something hot graze against my hip."

McMullin "loved to work," but "what he did for work was not solely what defined him," his obituary states.

"Whether meeting new people, attending music events, furthering his education, or helping others — Joe was viewed by all as a brave, kind, and compassionate person in their life. He was a beloved son, loving brother, proud uncle, and the most loyal friend," his family wrote.

Chambers was also injured in the crash and was wheeled into court Wednesday wearing a sling on her arm. A judge set her bond at $50,000.
