A young Google software engineer died at his desk Friday night in the company’s New York headquarters.

Authorities say there were no signs of physical trauma and no indications of a criminal act. Krulcik’s death is being investigated by the New York City Medical Examiner. News sources say Krulcik had no history of health or substance abuse problems.

The Carnegie Mellon University graduate interned at Google several times before being hired full-time after graduating with a degree in computer science.
