Three members of an Allen family were killed when their van collided head-on with a car on a highway in a remote area of northern Arizona.
The Arizona Department of Public Safety identified those killed as 60-year-old Rebecca Simpson Stryker, 56-year-old James Lee Stryker and 16-year-old Travis Stryker.
A twin brother of the teenager, 16-year-old Austin Stryker, was seriously injured and hospitalized in Flagstaff. NBC 5 learned that his sister flew to Arizona to be with him.
The family was heading to a hockey tournament for the twin boys in Las Vegas when the crash happened.
The DPS said a car that crossed the center line first collided with a second car before it collided with the Strykers' van.
The DPS said two people in the car that crossed the center line also were injured.
The accident occurred on US 89A near the Vermillion Cliffs National Monument.
“He's out there by himself and what it must feel like, I can't even imagine," said Coach Jeff Mewett. "I can't even try to imagine that."
The DPS said cause of the accident is under investigation.
Austin Stryker has been communicating on Twitter, saying he is grateful for his friends and the people of Allen. He is encouraging his teammates to win the game in Las Vegas.
“It has turned into now we want to go and we want to go win it for Travis,” said Bryan Ford, President of the Dallas Junior Hockey Association.
The Dallas Junior Hockey Association has started a fund for the Stryker family. You can find it on their website at www.djha.com.
A family friend also told NBC 5, Austin could be back in North Texas as early as this week. The Dallas Stars plan to honor the Stryker family at Friday’s home game versus the Chicago Blackhawks.
