Actor Jonathan Joss — best known for his voice work on the iconic animated TV comedy “King of Hill” — was shot dead by a neighbor in Texas, according to police.

Joss, who voiced “John Redcorn” on the long-running cartoon, got into an argument with the neighbor at his home in San Antonio Sunday night when the neighbor pulled out a gun and shot him several times, police said.

The unnamed gunman then fled in a vehicle but was arrested just a block away.

Joss died at the scene despite paramedics’ best efforts to save him, TMZ reported.

He was 59 years old.

In addition to his character on “King of the Hill,” Joss, who has Native American ancestry, also had a recurring role on “Parks and Recreation” as Ken Hatote.
