They called me i have to talk to a bank investigator
That would be a bad idea since the bank investigator could turn around and report what you say to the police.
I agree with CTU that you should be talking to a criminal defense attorney before you talk to the bank investigator because anything you say can and will be used against you and a bank investigator who is not a cop, doesn't have to tell you that.
Don't talk to anybody else about it, not even your husband, and stay off the internet.
