The baby son of a police officer has died after being left inside a vehicle in central New York, where outside temperatures were around 80 degrees.

Oneida County sheriff's deputies say Rome police officer Mark Fanfarillo found 4-month-old Michael inside the vehicle Monday afternoon and called 911.

The child was rushed to Rome Memorial Hospital, where he was pronounced dead.

Authorities say Michael was left in his father's vehicle for an "extended period of time." Michael's father, a 10-year veteran of the Rome Police Department, was responsible for watching him at the time.

An autopsy was scheduled for Tuesday to determine the cause of death.

No charges have been filed.
