HILLSBORO, Ore. >>  The father of an Oregon baby who died after being left in a parked car told police that he was supposed to take her to daycare but forgot and went to work instead.

Investigators on Friday were still trying to sort out what happened Thursday in an Intel Corp. parking lot, Lt. Mike Rouches of the Hillsboro police said.

The father parked the car about 11 a.m. Authorities were called about 5 p.m., Rouches said.

The 6-month-old girl was unresponsive when emergency responders arrived, and the child had no obvious injuries, Rouches said.

He said it was likely an autopsy would be done on Friday, but it was uncertain when a medical examiner might complete an examination of the results and establish a cause of death.

Investigators were interviewing the parents, who haven’t been publicly identified, and the father’s explanation should be considered preliminary, Rouches said.

The father took the baby to a doctor’s appointment on Thursday morning and afterward was supposed to take the child to daycare.

The mother was performing CPR when firefighters arrived, fire spokesman Storm Smith said.
