The hazard lights of the Mercedes and the Chevrolet SUV were both flashing on a night when the weather was clear and traffic was light, police said in a search warrant in the case.

D. Michael Caudill, the commonwealth’s attorney for Goochland, declined to comment on the facts of the case on Tuesday.

Family members of the three victims in recent months filed separate lawsuits, each seeking more than $25 million in damages against Carr and her law firm, Kalbaugh, Pfund & Messersmith. The separate lawsuits from each family claim that at the time of the accident, Carr was driving a vehicle that was provided to her by that firm for business use.

The three family’s lawsuits accuse Carr of driving too fast and disregarding the Mercedes’ emergency lights, which the litigation says were visible from at least a half-mile away. The lawsuits accuse Carr of being negligent in how she drove the vehicle and the litigation alleges she caused the three deaths. The lawsuit filed by Xu’s husband also charges that Carr was texting in the seconds before the crash.

In written responses, an attorney for Carr and her law firm denied the allegations against them, and asserted that the defendants are not guilty of any negligence. Jury trials in the civil cases have been scheduled to take place in 2019 and 2020.
