JACKSONVILLE — A 50-year-old Jacksonville woman, and experienced diver, drowned while cleaning her backyard swimming pool last week.

In an interview with the Florida Times-Union, the victim’s husband, Steve Cox, noted his wife Angela was alone while vacuuming the pool last Thursday.

Later in the day, their 15-year-old daughter, who had been watching television inside, found her mother at the bottom of the pool, the victim of an apparent drowning.

Surprisingly, Cox told the Florida Times-Union his wife was an avid scuba diver.  He says his wife recently participated in 30 dives over a two-week trip to the Florida Keys.  However, to clean the pool, she wasn’t wearing any diving gear.  The couple cleans the pool once a week.

Cox says the couple would often stay at the bottom of the 9-foot deep end without oxygen to increase their lung capacity for future dives.

The Cox’s 13-year-old son started CPR on his mother but was unable to revive her.
