I've heard foxes, screech owls and much more....that's a kid in the back seat, IMO. The last sound faded away with the Doppler effect as the SUV disappears down the hill.
I was thinking maybe even the child is in pain and the driver is in a big hurry, pretty much running the stop sign but looking to insure no one's coming down the hill. If you're by yourself and the child is sick or injured you may still have to strap them in the car seat and that will really trigger their bawling...I was in that scenario once about 40 years ago.
Could as easily be throwing a fit, too.
