The Apple employee found dead at the company's California headquarters died of a self-inflicted gunshot to the head, police said on Thursday.
"The Coroner's office has identified the decedent as Edward Thomas Mackowiak, age 25. The Medical Examiner determined the manner of death was suicide and the cause was a gunshot to the head," the Santa Clara County Sheriff's Office said in a written statement.
Mackowiak's body was found Wednesday at Apple's campus in the Silicon Valley community of Cupertino.
An Apple spokesman declined to comment or say what Mackowiak did for the company, but a LinkedIn profile that has since been taken down listed him as a software engineer.
