An elderly man reportedly died Thursday after suffering a medical emergency on a popular hiking trail in California’s Sequoia National Park.
The victim was identified as 79-year-old John Francis Oliver of Henderson, Nevada, a suburb of Las Vegas, the Tulare County Sheriff’s Office said, according to Your Central Valley.
Oliver was found along the General Sherman Tree Trail, a one-mile path that leads to the world’s largest living tree, the General Sherman Tree, according to the outlet, citing the National Park Service (NPS).
First responders rendered emergency medical aid to Oliver at the scene, but the man was eventually pronounced dead in the park, according to SFGATE.

The man’s cause of death has also not yet been determined.
