A new ploy has police warning that identity thieves could be stealing your mail without even getting into your mailbox.

Typically, ID thieves will break into cars or mail boxes to steal valuable information -- but now detectives say the crooks have figured out a way, to have your mail forwarded right to them.

This week, Gresham Police arrested 26-year old Amber Carrillo, who faces 86 counts of identity theft.

According to police, Carrillo would go to the post office and fill out a change of address form, noting the victim's name and listing her apartment as the forwarding address. Within days, police said she would receive the victim's mail, including sensitive financial documents, even W2 tax forms.

Police said it’s just the tip of the iceberg.

One of the victims alerted authorities after she stopped getting mail. But by that time, the ID thief was off and running.

"I guess I never realized how simple it was,” victim Nola Christos said. “You always hear so much about identity theft, thinking it is going to happen to the other guy but, yeah, it was really quite simple."

Police said if you stop getting mail, or get unexpected notice that your mail is being forwarded, alert the post office and police right away.
