After a controversial trial, an Oklahoma man makes a final plea to avoid execution

Tremane Wood was convicted of a murder his brother had confessed to. Now a Republican governor will decide whether he dies on Thursday

It may be about to execute him, but Oklahoma's department of corrections hasn't even spelled Tremane Wood's name right: it lists him on its official website as Termane" Wood.

For 16 of his last 21 years in prison, following his conviction for the murder of 19-year-old Ronnie Wipf, he has been confined, often alone, to a series of windowless concrete cells in the state penitentiary in McAlester, Oklahoma, in an underground block that prisoners have compared to a tomb.
