Investigators call her the "bad hair bandit.'' Every time she holds up a bank, she's sporting a different wig or hairstyle, none of them good.
Authorities say the woman has robbed 18 banks in the Oregon and Washington state areas since December 2010.
She has reportedly gotten away with thousands of dollars. Fortunately, no one has been hurt.
The suspect may be branching out. The FBI says a woman with bad hair robbed a bank in Montana last week.
