A South Bay family is dealing with the heartbreaking loss of two young children this weekend.
The Santa Clara County Sheriff's office reports two toddlers were found unconscious in a family pool in the town of San Martin.
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.
The toddlers were flown to Stanford Medical Center on an emergency helicopter. One died during the flight. The second child died Sunday morning.
The San Jose Mercury News is reporting they were twin sisters who would have turned three in December. Neighbors told the paper the family had moved there three years ago and called them a private family.
Detectives are trying to determine how the children gained access to the pool, which is surrounded by a fence. The 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 10 acres property.
It is believed the two were siblings, but authorities did not give names or exact ages of the children.
