King of the Hill star Johnny Hardwick has died aged 59.
The voice actor played Hank Hill’s conspiracy theorist next door neighbor Dale Gribble on the iconic animated series in 258 episodes from 1997-2010.
Hardwick was found dead at his home in Texas on Tuesday after police were called for a welfare check and found his body, reports TMZ.
According to the US news outlet, he was pronounced dead at the scene with no foul play suspected and a cause of death has yet to be confirmed.
In addition to lending his voice, the Texas native also served as a staff writer, story editor, and producer for the show, earning four Prime Time Emmy nominations.
In 1999 he won an Emmy Award for his work as a producer on King of the Hill.
Apart from his role in the hit television series, Hardwick was also a voice actor for the movie Natural Selection in 1999 and a producer for the film Shadows of Sofia in 2019.
In recent years, he created a YouTube channel which saw him perform song parodies and monologues in the style of Gribble, while wearing his famous shades and orange cap.
