Edward L. Neal was sentenced to 60 years as a habitual offender following a trial in 2010.
Authorities say Neal robbed Samuel Livingston, 83, in December of 2006 after posing as someone who wanted to rent property from Livingston. Authorities say Livingston was shot in both legs while trying to get away from Neal.
Neal initially denied involvement in the incident, but later gave a statement to police about what happened. Prosecutors say Neal waived his Miranda rights.
In his appeal, Neal argued the trial judge was wrong not to throw out the statement he gave to police.
The Appeals Court this week rejected Neal's appeal.
