WATSONVILLE, Calif. - A mother and daughter have been arrested following the death of a three-month-old infant who was at a home day care, which the Monterey County Sheriff’s Office said was operating without a license.
Sheriff’s deputies and emergency crews were called to a home on Hillcrest Road in the community of Royal Oaks on Saturday morning.
Not conscious, not breathing
"The reporting party stated the patient was a three-month-old infant that was not conscious and not breathing," sheriff’s officials said in a news release.
Emergency crews initiated lifesaving efforts and rushed the baby to a hospital, but the baby did not survive, sheriff's officials said.
Unlicensed day care
On Saturday night, the sheriff’s office said that the home they were called to was being used as a day care, but investigators said it was not licensed to operate as one.
Officials also said that detectives learned the business was taking in as many as "30 children of various ages at a time."

Mother, daughter arrested
Based on their findings, the sheriff’s office said detectives arrested the two operators of the day care: 62-year-old Maria Marquez and her daughter, 35-year-old Johanna Marquez.
The women were booked on charges of involuntary manslaughter, felony child endangerment, and operating a child day care facility without a license.
The mother and daughter were each placed on a bond of $50,000.
A search of the Monterey County Sheriff's Office in-custody log did not turn up Maria Marquez's name on Monday. It did show Johanna Marquez as being in custody.
What we don't know:
There’s no word yet on the infant's cause of death.
Officials said that the investigation was active and ongoing.
They urged anyone with information related to the case to contact the Monterey County Sheriff’s Office.
