Each and every time a guy disappears, the hypothesis always comes up sooner or later, that he was hit by a car and the driver disposed of his body.
Sure, it can happen, but so far, I have never personally encountered such an actually proven case where that has de facto been determined to have happened.
I know of the case of Erica, and it is possible, but firstly, the person, Brandon, recanted his story that she had been accidentily hit, and secondly her body was not found buried at the spot where he had claimed that Erica had been buried after the accident, when the authorities investigated the spot.
So, while it could well be what did happen to her, her destiny is nevertheless not a concluded fact.
Now, the following, on the other hand, are something as rare as examples of two
confirmed cases where the driver of a hit and run have
sort of taken the body with them:
The first case is the killing of Anna Lewis, hit by the driver Jose Santiago. When she was hit by the car, it happened with such a force that the upper part of her torso flew of into the vehicle, where it then remained in the backseat until the driver was arrested, with blood and "matter" all over the place:

In the other case, the driver, a woman by the name
Chante Jawan Mallard, struck 37-year-old Gregory Glenn Biggs, a homeless man, with her car. The hit was so powerful that his left leg literally flew off and landed on the dashboard while his body flew straight through into the windshield where it got stuck: http://murderpedia.org/female.M/m/mallard-chante.htm

Why I describe the graphics of the above cases, is to show that a hit and run is not so neat and clean as people might think; on the contrary it leaves one hell of a mess, and it
will also leave evidence both on the spot for the accident as well as on the vehicle, and even if not noticed immediately, then later when driving around with it.
The authorities also searched the area where they had traced Brandon's mobile phone, but found no trace of him. No blood, no mess, nothing. And no demolated cars were neither reported driving around or after that time
For this reason and in combination with other circumstancial details of the case, it must be considered extremely unlikely that a hit and run would have happened, without any evidence left whatsoever given the circumstances, and not the least as Brandon was out walking in the
field, not the road, when the call abruptly ended.
