NAPA — Authorities say a worker at a California vineyard has died in an accident involving a grape-harvesting machine.

State fire spokesman Bruce Land said emergency crews responded Monday to a report of a worker stuck inside the equipment at the Napa-area Deconinck Vineyards.

KPIX-TV reported 49-year-old Leon Marcelo Luna died at the scene.

The station said Luna’s family reported he was working next to the device when a piece of his clothing got caught and pulled him into the machine.

Cal/OSHA, the state’s workplace safety agency, will investigate.
