Jonathan Joss has died at the age of 59.

The King of the Hill voice actor was shot and killed on Sunday, June 1, in San Antonio, Texas, police confirmed to PEOPLE. According to police, authorities were dispatched to a shooting in progress at around 7 p.m., where they found Joss lying “near the roadway.”

Despite attempting “life saving measures” while waiting for EMS, when paramedics arrived, they pronounced Joss dead at the scene.

Officers quickly found and detained a suspect, 56-year-old Sigfredo Alvarez Cejam, who had fled the scene in a vehicle. PEOPLE can confirm that the suspect is a neighbor of Joss. He has now been booked for murder, and the investigation is still ongoing, per police.

TMZ was first to report the news.

Joss was best known for his voice role as John Redcorn in King of the Hill, which aired in the late ‘90s and early 2000s. He took over for the original actor, Victor Arron, in season 3 after he died in a car accident in 1996.

Joss was set to return to the newly announced revival of the hit animated sitcom, which is set to premiere on Hulu in August and has already begun recording.

Last week, Joss attended the ATX TV Festival, where he watched his co-stars ​​Pamela Adlon (Bobby Hill), Lauren Tom (Kahn “Connie” Souphanousinphone Jr.), Toby Huss (Cotton Hill, Dale Gribble) and one of the show’s new writers Saladin K. Patterson as they discussed the upcoming project during a panel.

Just hours before his death, Joss posted a video on Instagram talking about how the “reboot is up and moving” as he walked around Austin, Texas.

In addition to King of the Hill, Joss was known for his recurring role as Chief Ken Hotate in Parks and Recreation, and has also appeared in Tulsa King, Ray Donovan, True Grit, The Magnificent Seven, among others.
