Jonathan Joss, the “King of the Hill” voice actor shot and killed Sunday, was a deeply difficult man whose demons helped result in his tragic destiny, his ex-girlfriend tells TMZ.

Brandy Trejo, who dated Joss for 13 years through the peak of his profession, tells us … Joss was probably the most “self-destructive individual” she ever met … and to her, it appeared like he could not stand it when one thing good occurred to him.

What’s extra … Brandy says she witnessed him drive his neighbors loopy for years together with his outbursts and outlandish conduct … so when she discovered a neighbor allegedly killed him in an argument — she was not shocked.

As we beforehand reported … Sigfredo Ceja Alvarez bailed out of jail on Wednesday, and will likely be confined to deal with arrest awaiting trial, after he allegedly fatally shot Joss Sunday night — he is been charged with homicide. The actor’s husband, Tristan Kern de Gonzales, known as the taking pictures a homophobic hate crime … regardless of Tristan’s assertion, San Antonio police declared there isn’t any proof of a hate crime.

As Brandy explains … Joss was a unfastened cannon who preferred to make hassle — clearly not an excuse for killing him! — and she or he believes he had undiagnosed psychological well being points that he solely made worse with medication and booze.

She wasn’t simply his girlfriend from 2006 to 2019 … Brandy tells TMZ she turned the actor’s unofficial assistant and handler throughout that interval of his profession … and it was as much as her to chill him off when he went right into a random rage on a set.

Joss was greatest recognized for enjoying John Redcorn on the animated TV sitcom “King of the Hill” … however he had almost 50 TV and movie credit to his identify, together with in big movie productions like “True Grit” and “Magnificent Seven.” And Brandy tells us … they have been kicked off plenty of these units — ‘trigger Joss would begin hassle with a star or a director.

Brandy’s reminiscences with Joss weren’t overly constructive — she says he was very emotionally abusive and destroyed her self-worth — and but, there have been pockets of happiness when he can be a great man and take her on his enjoyable Hollywood adventures.
