Last year there were 94 bank robberies in Philadelphia. That averages to one every three or four days.
The reasons are as different as the descriptions of the men and women who pull off the heists.
Investigators say some robbers are calculating pros, while others are desperate and looking for drug money.
At the FBI robbery squad office, its status board lists 14 cases. Eight of them, the FBI says, were the work of four individuals scattered across town.
A surveillance camera captured one man in his 20's or 30's. He changes his hat and sunglasses between jobs, and has robbed a trio of banks in the Northeast.
In Center City, a man thought to be in his 40's with salt and pepper hair has some nerve targeting a bank just one block from the FBI office. He hit it twice last month.
Robber number three is described as a man in his 30's. He had a silver handgun when he hit a Wachovia Bank on West Erie Avenue in February.
He was bundled up, but agents hope the oversized writing on his hood might ring a bell.
The fourth bank robber police are looking for was wearing a unique hat that the FBI hopes someone might recognized.

"We may not need a name. Someone says "I recognize that person around a store, I have seen him in my neighborhood," suggested J.J. Klaver of the FBI.
