LISTEN: Sheriff's Audio Dispatch Describes Body Found on Apple Campus

No suspects are being sought in his death, and no one is in danger, sheriff's officials said, adding that the campus at 1 Infinite Loop is open. Investigators have not confirmed information in apparent police dispatch recordings in which authorities describe the scene.

"Through further investigation, they determined there was no other individuals involved and they believe it was an isolated incident. There was no one else on campus or in the public at risk," Sgt. Andrea Urena with the Santa Clara County Sheriff's Department said at a press conference at the Apple campus Wednesday afternoon.

Sheriff's deputies were dispatched to the campus after receiving a call about 8:35 a.m. about a person down at 1 Infinite Loop, Urena said. "When they got there, they determined he was deceased," she said. Urena declined to comment on the cause and manner of death.

The county coroner is now in charge of the investigation and will release more information once it is completed. Urena would not comment on whether a weapon was involved or if the death was suicide or natural.

The Santa Clara County Fire Department said crews were called to the scene but were then waved off and never went on campus. The body was reportedly found in a conference room Wednesday morning.

Apple did not respond for comment sent via email.

Dispatch recording obtained from Broadcastify.com indicates that a female employee on the Apple campus was escorted out of a building by security Wednesday morning, and had sustained an injury to the head, possibly from a gun. Two minutes later the dispatcher talks about a dead body found in one of the conference rooms, with a gun nearby. How the woman is related to the man's death is not clear.

Urena would not confirm any of the information in the dispatch audio, or comment on whether the incident stemmed from a disgruntled employee.

NBC Bay Area chopper footage showed at least one sheriff's car on campus before noon.

On Tuesday, Apple announced its first revenue drop since 2003, sending the company's stock price down more than seven percent in extended trading.
