Jason Hairston: Former NFL Player and Friend of Donald Trump Jr.

DIXON, California – Another suicide linked to possible brain injuries related to football has left a member of the Hall of Fame of UC Davis and the former 49er of San Francisco. CBS San Francisco reports that Jason Hairston was also the founder of a successful KUIU hunting clothing company based in Dixon, California.

The company, valued at $ 50 million, has posted a solemn farewell photo of their black and white founder on their social media sites.

Just a few weeks ago, Donald J. Trump, son of Donald Trump, president of Donald Trump, posted photos of the two people during a hunting trip to Canada.

"Thanks for the friendship and memories of my friend, I will miss you."

Hairston had recently been appointed to a position at the federal government's Interior Ministry.

His success in business has followed a short career as an NFL linebacker and a career in college football at the Hall of Fame at UC Davis.

Hairston had spoken openly about his fights with symptoms of what he believed to be the ECU, a brain disease associated with head trauma.

His friend George Visger, also a former 49er with brain injuries since his playing years, says Hairston had shared his difficulties with the symptoms.

"We are baseball players and you have that mentality that you know that it's not going to lead me," said Visger. "But he also talked a lot about it for a few years."

Visger, now receiving brain injury treatment at the Center for Neuro Skills, says Hairston's commercial success after football shows how brain damage can be difficult to diagnose.

"You know, we have a saying in the world of brain damage," said Visger. "If you saw a brain injury, you saw a brain injury, everyone is different."

Hairston leaves a wife and young children and friends around the world. All asking, "why?"

"It was not their father, their husband, their brother and their friend, who thought about it," said Visger. "It was a broken part of his brain."

Jason Hairston has been a success in life. His death is another painful reminder of the long-term impact of football history.

The family issued a statement on the KUIU website requesting that donations be made to support CTE-related research at the Boston University Legacy Foundation instead of sending flowers.
