Jeff Garcia, the comedian and voice actor best known as the voice of Sheen in “Jimmy Neutron,” died after a series of serious health complications. He ultimately passed away in a Southern California hospital after being taken off life support.

Cause of death

Reports from his family and news outlets state that Jeff Garcia’s death followed months of medical problems, including a brain aneurysm earlier in the year that led to a fall and head injury, a subsequent stroke, pneumonia, and then a collapsed lung. These complications progressively weakened his health and led to repeated hospitalizations.

Final hospitalization

In late November 2025 he was hospitalized with pneumonia and was briefly discharged after showing some improvement. In early December he returned to the hospital with severe breathing difficulties, and one of his lungs collapsed, leading to him being placed on life support and then removed from it with his family present.
