Investigators have identified the man killed in a head-on collision Friday night.
Gary Carruth, 41, was killed after he lost control of his pick-up truck on I-10 near Camp Bullis Road.
Authorities said the truck crossed the median and hit an 18-wheeler head-on.
Carruth and his 13-year-old daughter, Sommer Jewel Carruth, died at the scene.
His two other children, ages eight and four, were both flown to University hospital.
“It’s a nightmare,” said Carruth’s fiancée Amy Freeman. “To think, what you thought could be your family, you just don’t believe this is happening.”
Freeman said she spoke to Carruth over the phone after he and his children left his mother’s house in Boerne.
Carruth told her they were going to stop at H-E-B on the way back to San Antonio.
Freeman said she began to worry when she tried calling her fiancé a second time.
“I thought they were just in the store, and they didn’t hear the phone,” she said. “I left a message just saying, ‘I’m worried about you guys, call me back. ’”
After failing to get in touch with Carruth several more times Freeman said she went online and saw news about a car accident.
“I just felt in the pit of my stomach that something was wrong.”
The couple met in junior high. They lost touch be reconnected decades later. They got engaged last October.
Freeman said Carruth was truly a hero. He served two tours in Iraq and survived two explosions. He received military honors for his service.
Freeman said above all else, her fiancé was a good father.
“He just adored his kids. That was his life,” she said.
Investigators are still trying to determine what caused Carruth to lose control of his vehicle.
