At about 4:50 a.m. Wednesday, Wilcox was preparing her report for air while Williams was setting up the lighting. The pair's morning routine was then suddenly upset by a massive eruption of gunfire.
Williams instinctually dove for cover underneath the back of the live truck while Wilcox slid down in her seat.
"I slid down in the drivers seat and started praying. All I could think about was my 1-year-old daughter and my husband," said Wilcox. "It was terrifying. The bullets sounded like they were right outside the window of my truck."
Someone had opened fire along southbound Interstate 35E near Continental, spraying an estimated two-dozen rounds over the area.
"I would say it lasted 30 seconds," said Williams. "It just seemed like a long time. All I could think about were my little girls."
Neither Williams or Wilcox were hit, but the gunfire did hit a passing driver, who then spun out of control, hit a freeway barrier and then crossed several lanes of traffic before coming to rest in the median.
Lt. Albert Martinez, with the Dallas Police Department, said the victim was struck multiple times, though he was able to walk to the ambulance and it appears the injuries are not life-threatening. Police said at least one bullet was lodged in the driver's hand and that another grazed his head. He was transported to Parkland Hospital for treatment.
Investigators said the victim is not cooperating with police, though they did determine that shortly before the shooting he had left a late-night club and was traveling on Stemmons Freeway when the shots were fired.
There were no other reported injuries from the shooting.
