PULLMAN, Wash. (AP) — Washington State quarterback Tyler Hilinski has died from an apparently self-inflicted gunshot wound, police said.

The 21-year-old Hilinski was discovered in his apartment after he didn’t show up for practice Tuesday. A rifle “was recovered next to Hilinski and a suicide note was found,” according to the Pullman Police Department.

“We are deeply saddened to hear the news of Tyler’s passing,” Washington State coach Mike Leach said in a statement. “He was an incredible young man and everyone who had the privilege of knowing him was better for it. The entire WSU community mourns as thoughts and prayers go out to his family.”

Hilinski was the presumptive starting quarterback going into next season. He started Washington State’s Holiday Bowl loss to Michigan State after senior Luke Falk was unable to play due to a wrist injury.

“The tragic news today surrounding Tyler Hilinski is devastating to all. Tyler was a tremendous individual, great friend and teammate, and he will be deeply missed. Our hearts go out to his family and friends,” interim athletic director John Johnson said.

Hilinski appeared in eight games during his sophomore season, throwing for 1,176 yards and seven touchdowns.
