Stackowitz was serving a 17-year sentence for robbery by force when he escaped the infirmary at the Carroll County Prison Work Camp in Carrolton, Georgia, on August 22, 1968, according to US authorities.
He was finally recaptured on Monday in Connecticut, the US Marshals Service said in a statement.
A break in the case came after investigators found a possible alias that Stackowitz was using.
"Investigators then discovered an address in Sherman, Connecticut, which was linked to the alias," the service said.
He is currently in jail in Connecticut awaiting extradition back to Georgia, CNN reported.
