So,if the person using the credit card is the person who killed her,than the killer is a woman? I would think the gas station attendent,would be skeptical if a male was using a female's credit card. For some reason I automatically thought it was a man.Just wanted to add, I think we all kind of know that the person who did this is not the best thinker as they went to a gas station (I think everyone in the world knows the gas stations have security cameras) and used her credit card.. Wonder if they are still trying to use her cards anywhere you know... I would be checking to see if they like sold the credit card numbers online ... like that dateline report where they had credit card thieves selling the numbers online and dateline did a sting on em
