This afternoon at about 2:56, Blackhawk Deputy Sheriffs responded to a home on East Ridge Court regarding a woman who was in a swimming pool and was not breathing.
When the deputy arrived, he was told a child, who had also been in the pool, was already en route to San Ramon Regional Medical Center (SRRMC).
An adult female was being attended to by fire personnel in the backyard and later transported to SRRMC.
They were both later pronounced deceased at the hospital. They are not being identified at this time.
It was not revealed if the pair were related in any way or what, if any, activity was underway at the time of the drownings.
The Office of the Sheriff is conducting an investigation into the deaths. At this point, it does not appear suspicious and there are no signs of foul play.
