the car was only in about 5 feet of water, upside down- one of the tires was above water when they found it
she was found in the back seat, presumably in an air pocket
Just telling you what the police report said . . . and it's also mentioned in a detailed book. Maybe with Ted in the car, the car's nose or butt was dipped further into the water. You might be seeing a picture of the car being razed out of the water. She drowned with her neck stretched at an odd angle trying to keep breathing a small pocket of air.
