SAN DIEGO - The medical examiner will conduct more tests to determine how a woman died on the grounds of a Mission Bay hotel in August.

62-year-old Gale Yonai of Montebello was found shortly before 11:30 p.m. on Aug. 17 face down, unconscious and unresponsive, in a man-made pond on the grounds of the Paradise Point Resort and Spa in the 1400 block of Vacation Road, according to the county Medical Examiner's Office.

Medics pronounced her dead at the scene.

The medical examiner's office has conducted an autopsy but concluded that toxicology tests need to be done to find the exact cause of death.

Based on their preliminary investigation, police said Yonai left the couple's rented room to smoke while her husband was napping around 10:30 p.m. Thursday. The husband told police he called hotel security when he awoke about an hour later and could not find her, then joined in searching for her.

Police ruled the death as suspicious.
