Houston Tumlin, a child actor who starred alongside Will Ferrell in “Talladega Nights: The Ballad of Ricky Bobby” nearly 15 years ago, died yesterday at the age of 28.

He passed away from a self-inflicted gunshot wound to the head at his home in Pelham, Alabama.

In the 2006 comedy “Talladega Nights: The Ballad of Ricky Bobby,” Tumlin played the brash and foul-mouthed 10-year-old Walker Bobby, son of Ferrell’s Ricky Bobby.

It was the only movie he appeared in.

Tumlin also served in the Army’s 101st Airborne Division at Fort Campbell in Kentucky.
