I can also understand the psychology behind the perp wanting to place back the victim where he picked her up maybe. Say , for example, he picked her up close to the Hitchin Post. Maybe saw her starting to walk and followed in his vehicle sensing her vulnerability as sunset crept closer. At night then he placed her back there, maybe to make it look like she never was picked up there "tried to get in a vehicle but never quite made it to one". In his mind it was also a way of cancelling what he had done ; as if pretending she were still there all along next to the road like he never picked her up. Criminals experience a strange sense of guilt sometimes
