Family of 4 Revealed as Victims of Crash on Texas Highway After Truck Driver Allegedly Fell Asleep: Reports

Four members of the same Fort Worth family have been revealed as among the victims of a recent multi-vehicle crash in Texas.

Shaun and Zabar McKellar died along with their 15-year-old son Kason and grandfather Billy McKellar, 79, when a semi-truck crashed into several vehicles on Interstate 20 in Terrell on Saturday, June 28, NBC News and CBS News reported, citing the Texas Department of Public Safety. 

Evan McKellar, 20, was the only family member to survive the crash. She had been riding with her family in a Ford F-150 truck at the time and was sent to the ICU at Parkland Hospital with critical injuries, according to the outlets.

The fifth victim who died in the crash has been identified as the driver of another vehicle, 49-year-old Nicole Gregory from Dallas, per NBC News. She died at the scene.

The crash happened after a semi-truck hit two 18-wheelers and three passenger vehicles, causing a “mass casualty” event, CBS reported at the time of the incident, citing the Terrell Volunteer Fire Department.

Alexis Osmani Gonzalez-Companioni, 27, allegedly told police that he fell asleep at the wheel before crashing into the back of a pickup truck carrying five people at around 2:40 p.m. local time, KLTV, CBS News Texas and the Fort Worth Star-Telegram previously reported. 

Gonzalez-Companioni was charged with five counts of manslaughter and an additional count of aggravated assault with a deadly weapon related to the crash, PEOPLE confirmed. He is currently in custody at the Kaufman County Jail.
