The children were found inside a small SUV, which the coroner said was a "family car." Both were pronounced dead at the scene.
Rutherford said the daycare staff was not involved or complicit in the death.
When asked by reporters, Rutherford wouldn't say who had driven the children to the daycare, other than saying it was a "parent," citing the ongoing investigation by the Richland County Sheriff's Department. She said at this point, it's not known if this was an unfortunate accident, so she does not want to identify anyone until it's clear what actually happened.
She said the children were enrolled at the daycare and supposed to be at the facility all day. According to Rutherford, it's believed the children were first put in the SUV in their rear-facing child seats between 7:30 and 8 a.m. Wednesday, and the SUV came back to the facility at 5:30 p.m.
