Matthews and Dorsey travel "upstate" for approximately 90 minutes (no mileage stated) to investigate the car thefts, yet they call in to the same headquarters. More than likely, they would have traveled beyond the radio range of their station and would have to call another station.
When the thieves talk on the phone, the license plate is stated as HEW-466. However, later when Matthews and headquarters radio several times, the plate number is described as HEW-766.
As the male and female car thieves walk up from the lake after exchanging keys, a crew member is visible moving inside the stolen car, causing the car to shake.
