A 51-year-old man died on Sept. 1 after coworkers found him facedown in a 10-foot-deep trench in a construction project on on the corner of 116th Avenue and 4th Street.

The man, identified as Phillip Cruz, was found facedown in two feet of water at the bottom of the trench around 9:45 a.m. His cause of death was later identified as drowning, according to the medical examiner’s office.

Construction workers removed the man from the water and began CPR. The Bellevue Fire Department responded to the scene and were able to resuscitate the victim and transport him to Overlake Hospital, where he later died.

Coworkers said he had been acting normally, but hadn’t been seen for 10-15 minutes before he was found. His death is reportedly still under investigation by the Bellevue Police Department.
