Oh,that's bad,without the battery,hm,so it wouldn't ping.Well,if she was taken,they had time to take the battery out and obviously wouldn't be the first time if they knew to do that.But,on the otherhand,if she was angry she left the concert to walk,seriously otherwise it makes no sense her walking,maybe seeing a school setting she would feel more comfortable in getting a ride from someone there.But,could have still been being followed from the concert and that was their opportunity to take her.One could have had her in the vehicle and the other took battery out and threw purse and cell out.She would have had to be fighting and wouldn't have let someone throw her cell and purse if it was one person.IMO Unless she was kind of wasted from drugs or alcohol.
Um,I don't know if anyone has brought this up and I hate to,the outfit sounds cute for a college scenario,but at night in Charlottesville walking on the street,a person could have perceived her as a lady of the night,KWIM.I'm sorry,I know that sounds bad and she is not,she seems like a sweet pretty school girl who made a bad decision is walking.but men driving around looking for that in a big city,would easily mistake this.
