The husband of 53-year-old Ching "Ping" Chen flagged down a Contra Costa County Sheriff's Deputy just before 9:30 p.m. Tuesday night to say he hadn't seen his wife since she went outside to water the plants two hours prior.
The couple's home is on Beaver Lane.
Sky7 flew over it Wednesday afternoon and saw a search boat docked behind the house.
Officials say Chen was last seen wearing a light green tank top, green shorts and pink sandals.
UPDATE: Chen's body was found in the water by sheriff's search divers on Wednesday night.
