Diana has been a victim of check forgery fraud (someone used a computer to create a copy of her checks). They were able to withdraw $6,300 from her checking account to buy a car and apparently had a copy of her signature (she says they were able to make it look like her own hand). She was upset because the police would not take a police report and told her they're inundated with fraud cases. She also thinks the person works for the check sales company she used because the fraudulent check was cashed recently after she ordered new checks.
Diana's name has been changed to protect her privacy.
