The voiceover world has lost another of its stars. On Tuesday night, per TMZ, Jeff Garcia was taken off of life support in a Southern California hospital. The comedian, primarily known for his role as fan-favorite Sheen Estevez in Jimmy Neutron: Boy Genius, had dealt with several health issues in the past months. According to what his family told the outlet, he suffered an aneurysm in the spring. And though he recovered then, he sadly suffered a stroke just a few weeks ago. On November 20, he was also hospitalized with pneumonia.
