The Santa Clara County Sheriff's department released new details about the double drowning of two children this weekend in San Martin.
The victims were twin sisters who were two months shy of their third birthday.
Their parents called 911 after the shocking find just before 4 p.m. Saturday. Emergency crews arrived within minutes and took over for the parents in their efforts to revive the children using CPR.
Police say their father was working on the family property when he discovered them both in the pool
He jumped in and got them out and then yelled to his wife, who was inside the house, to call for help.
They started CPR until help arrived.
The toddlers were first brought to St. Louise Hospital in Gilroy and then flown to Stanford Medical Center on an emergency helicopter. One died during the flight. The second child died Sunday morning.
Aspen Niva-Wiggle and Annalise Niva-Wiggle were just 34 months old.
Neighbors told the San Jose Mercury News the family had moved there three years ago and called them a private family.
This incident is being investigated as an unattended death, but the sheriff's office said it is believed it will be classified as an accidental drowning.
The home is the Rancho Robles subdivision located in the Hills south of Morgan Hill. The family reportedly keeps horses and has corrals on their property.
