‘King of the Hill’ Actor Jonathan Joss Murder Suspect Claims Self-Defense in Shooting

The man accused of killing “King of the Hill” voice actor Jonathan Joss is claiming self-defense — according to his lawyer.

Attorney Nico LaHood says Sigfredo Ceja Alvarez — known as “Freddy” to friends and family — is pleading not guilty, and insists he’s innocent, adding … “It’s difficult for anyone who’s been accused of something they didn’t do, especially murder.”

Alvarez was arrested earlier this month after allegedly shooting and killing his neighbor, Joss, during a heated argument in San Antonio, Texas, according to cops. The late actor’s husband, Tristan Kern de Gonzalesimmediately dubbed it a hate crime — claiming homophobic slurs were hurled by Alvarez before the fatal shot.

LaHood says his client is shaken by the accusations — insisting they’re not true and pointing out Freddy has a gay brother. He says despite it all, Alvarez has support from neighbors.

Alvarez posted $200,000 bail just days after his arrest in the headline-grabbing murder case — and now he’s under house arrest in Bexar County. He’s also facing random drug and alcohol testing, and is banned from possessing or using any firearms while he awaits trial.
