WEST PALM BEACH, Fla. -

Deputies are trying to find a woman responsible for three bank robberies in Palm Beach County.

The most recent robbery occurred Tuesday morning at a PNC Bank branch in Lake Park. The other two robberies occurred May 15 at a Wells Fargo branch in Palm Beach Gardens and less than two hours later at a SunTrust branch in Lantana.

Palm Beach County Sheriff's Office spokeswoman Teri Barbera said in each robbery the woman entered the bank, passed a note indicating she had a gun or bomb and demanded money.

She was seen leaving the SunTrust in a silver or gray vehicle.
