Coleman Nee, 42, admitted this week to handing a bank teller a note that said he would kill them and a customer if they didn't give him money, the US Attorney for Massachusetts said. The teller complied but slipped a GPS tracker in with the cash.
Nee only got to keep the money for about 20 minutes before police arrested him, the prosecutor said.
He faces up to 20 years in prison and a fine of up to $250,000 for the bank robbery. A judge is scheduled to sentence him on March 9.
