Superior, WI (NNCNOW.com)--- Four towns in Northwestern Wisconsin have fallen victim to unsolved bank robberies in the past 2 years.
According to the F-B-I's annual report on bank robberies in 2008, the feds identified just 40 percent of the perpetrators in nearly 7-thousand robberies.
Banks in Superior, Poplar, Stone Lake and Danbury have been all robbed with the suspects disappearing into thin air.
Going back to 2012 a woman robbed the M & I bank on Tower Avenue in Superior in broad daylight.
Police say she handed a note to the teller announcing the robbery and then left on foot with the cash....never to be seen again.
Then in December of 20-12, a masked man, brandishing a hand gun, walked into the National Bank of Commerce in Poplar, demanding money from the teller.
Along with handing over cash, the teller was forced to also hand over the keys to her car.
The robber and her car have not been found.
Then on May 14 of this year- two armed men robbed the Shell Lake State Bank in Stone Lake and sped away.
Then just 14 days later, an armed man robbed the Bremer Bank in
Danbury, Wisconsin. They too took off on foot, cash in hand.
Sergeant Ron Wilhelm with the Burnett County Sheriff's Office says the criminals usually take advantage of the fact that law enforcement presence is not readily available in rural areas and they know the banks are vulnerable
"I think it's just a crime of opportunity. And there's some planning I believe that goes in. I don't think there's too many bank robberies where they didn't case the place or any kind of recon work or anything like that prior to. So a lot of them know exactly what they're doing," said Sgt. Wilhelm.
According to the most recent F-B-I Bank Crime Statistics report available from 2011, more than 5 thousand banks were robbed in 20-11, with more than 38 million dollars being taken.
Authorities and the FBI are continuing to investigate the Northwestern Wisconsin robberies and following up on tips together.
If you have any information on the robberies, you can call any of the law enforcement agencies we talked about.
