As noted in the article here, after twenty-five years in prison [at some point, just keep on going], his last minute appeals failed. First, he tried to push the "no execution" line from 18 to 21. There is evidence for that but the law has not really caught up. Second, he argued the lethal injection drug (not the one getting so much attention recently) would clash with his other medication. Another fail on the "I want the firing squad" argument. Tinker tinker.
