Case #28104
Last month, Hudson National Bank was robbed by an unidentified man. The robber wore gloves, a hat, and a bandana that covered his face. A security guard attempting to stop the robber was knocked unconscious in a struggle. However, the guard managed to pull the hat from the robber's head. Witness accounts and security tapes led police to arrest three possible suspects. None of the suspects have alibis, but police are not certain which man is the robber. Using hair samples from the hat recovered by the security guard, the crime lab did a Southern Blot test.
