How far is Aberdeen from where Carlesha lived in MD? I have only heard Maryland and not the city she lived in while there.
Also, the fact that the card has not been used again means PERP knows for sure he's caught and he cannot risk it again. He's seen the news.
Both Leonardtown, MD. and a town named California, MD. have been mentioned. It looks like they are a little over 2 hours south of Aberdeen -- way down near the southern tip of MD.
