The director of a UC Irvine medical facility died of drowning after blunt-force trauma to her head, but the manner in which she died remains unknown, according to a county coroner's report.
Dr. Marianne Cinat, 45, was found dead in her pool at her Rossmoor home in June.
Cinat was a prominent Orange County surgeon and served as medical director for the UCI Regional Burn Center in Orange until her death.
The coroner's report says there were abrasions to Cinat's forehead and nose, and hemorrhaging at the front and crown of her head. Her lungs were filled with fluid.
