A Virginia family is “seeking answers” after an Oct. 5 car accident allegedly involving a foreign national ended with one son dead and another in an intensive care unit (ICU), according to a statement from the family.

Levi Gonderman shared the details of the crash in an X thread Thursday on behalf of his in-laws, the Jacksons. (RELATED: Illegal Trucker Accused Of Killing Three Was Given Commercial Driver’s License By California)

The post said the Jacksons’ sons — 21-year-old Zane, 16-year-old Toby and 14-year-old Boaz — were heading home from a Ninja Warrior competition in Northern Virginia. Zane was driving his brothers home on Interstate 95 south through Caroline County when the first of two alleged accidents occurred, the statement claimed.

The thread cites an unnamed witness who saw a driver fly by at top speeds before allegedly sideswiping the Jacksons’ car without braking. The car’s airbags deployed and its fuel pump was cut off, leaving the car stalled in its lane while the other driver pulled over roughly a quarter-mile up the road, according to the statement.

Apart from slight burns, the Jacksons’ sons were initially fine, according to the post. They turned on their hazard lights and called 911, and the dispatcher stayed on the line with the boys.

The family alleged that more than a minute after the first accident, a semi-truck struck the Jacksons’ vehicle.

“Zane passed sometime after. Boaz was unconscious with a traumatic brain injury. Toby had a minor fracture in his back. He was conscious and saw the whole thing. Toby saw Zane bleeding from the mouth and knew he was going to die. He then focused on trying to keep Boaz alive,” the post said.

Citing Toby, the family claimed he ran to the truck driver and tried to get him to call 911. Toby said the “truck driver barely spoke English and instead handed [him] the phone to talk to 911 dispatchers himself,” according to the thread.

The statement alleged the driver was a foreign national from Minneapolis, and he told police his dashcam had been broken for over a month.
