Gulfport police say a 61-year-old Louisiana man walked into the Harrison County Adult Detention Center and confessed to a 2005 bank robbery.
Sgt. Chris Ryle told The Sun Herald that Dale Evans Mott of Jennings, La., said he turned himself in because of the guilt.
Police had been unable to solve the Feb. 10, 2005, holdup at an AmSouth Bank branch until Monday.
Police booked Mott on an armed robbery charge. Justice Court Judge Diane Ladner set bond at $100,000.
