That's another one of the strange aspects. Supposedly she noticed the unauthorized charges and first contacted the stores asking them to preserve video tape of the purchases. She then called police.
The other is the fact that the people who claim to know the lady are saying the son didn't take the credit card, despite the fact police are on record confirming it was the son who was in possession of the card.
The info coming from those claiming to know the woman doesn't make sense based on information released by police.
Things are not adding up here.
