The FBI said it obtained a swab used to stop the bleeding and found that DNA matched Tucker's DNA on other evidence from a 2009 robbery at Monroe County Community Credit Union in Temperance, near the Michigan-Ohio border.
In a court filing, agent Robert Schmitz said he was aware of Tucker's bout in April in Toledo, Ohio, and obtained the "discarded" Q-tips swab.
      
Tucker's DNA matched DNA from a mask believed to have been used in the robbery and from the steering wheel of the getaway car, the FBI said.
