A volunteer firefighter from Collin County and his two children were killed in a wreck on Highway 78 near Wylie on Thursday afternoon.
The wreck, which occurred about 2 p.m., happened just south of Hwy. 78 and 205 when a van traveling southbound unexpectedly swerved into the northbound lanes and hit a Toyota sedan head-on.
Peter Hacking, a volunteer firefighter from Nevada, Texas, and his two children in the Toyota were dead at the scene. Three people in the white van were taken to a Plano hospital with serious injuries, officials said.
As news spread of what happened, multiple jurisdictions rushed to the scene.
"When something like this happens, we try to pull together as a community," said Trooper Kyle Bradford. "All law enforcement, fire department, everybody in the surroundings of Lavon coming out."
A call went out to all area firefighters to help cover the Nevada station as Hacking's fire family copes with the loss.
