Authorities plan on releasing more information during a press conference at 11 a.m. Thursday into the shooting death of an 18-month-old girl.
Investigators say she had been shot in the chest. When deputies responded to the home at 2370 Shore Road in an incorporated area of Hollister, they found a .357 magnum outside the home.
Although the undersheriff declined to identify the two people or their relationship to the child, the residents of the address are John and Cheryl Busch.
Police arrested two people, including Cheryl Busch. She is 39 and self-employed, according to the San Benito County Sheriff's Department.
The toddler is undergoing an autopsy.
Authorities spent most of the day processing the house as a crime scene.
