The Santa Clara County Sheriff's Department have officially stated that death of a man on Apple's campus earlier this week was not the result of foul play. Apple has also issued a short statement on the matter.
From The Los Angeles Times:
"We are heartbroken by the tragic loss of a young and talented coworker. Our thoughts and deepest sympathies go out to his family and friends, including the many people he worked with here at Apple."
The incident was first reported on Wednesday morning, when a man was found dead in one of the conference rooms on Apple's campus. While some reports indicated that another employee was injured, the sheriff's department says that no one else was involved in the unfortunate incident.
