The cause of death has yet to be released by authorities. Hullaby was last seen in Dallas on Friday heading westbound on I-30 at 6:23 pm.

Longhorns head coach Steve Sarkisian, who briefly coached Hullaby during his time in Austin, released a statement on his passing on Monday afternoon.

“It’s such devastating and tragic news to hear of Jaden’s passing,” Sarkisian said. “He was a great person and someone we all enjoyed being around, coaching and spending time with. All of our thoughts are with his family, friends and teammates, and we want to send our deepest condolences to them in such a difficult time.”
