LEESBURG, Va. — A food truck operator has been convicted of involuntary manslaughter in a crash that killed a Virginia mother of three.

On Friday, a jury in Loudoun County found Tony Dane guilty in a September accident that killed 39-year-old Erin Kaplan of Ashburn.

Authorities said Kaplan was driving her mother and children to the grocery store when Dane’s Great American hamburger food truck went through a stop sign and struck her station wagon.

Kaplan died at the scene. Her children each suffered multiple broken limbs.

The Washington Post reports that the jury recommended a prison sentence of nearly 12 years. A judge will make the final decision.

Dane, a conservative political activist, was charged in 2016 in Nevada with trying to extort a state lawmaker into changing his vote for Assembly speaker.
