De’Marchoe Carpenter was running out of time.

He’d lost an appeal, Oklahoma’s governor twice denied him parole, and his post-conviction lawyers had just informed him that a key witness died of kidney failure. They were forced to mothball his case. But here Carpenter was, waiting among a flock of prisoners in a penitentiary gymnasium with a heart full of hope.

For most of us, an incredible number of life events took place between 1994 and 2016. Marriages, babies, vacations, job changes.

For De’Marchoe Carpenter and Malcolm Scott, those 22 years included days that mostly looked the same — exercising, watching TV, writing letters, praying — all while incarcerated for a crime neither man committed.

They spent more than 20 years in prison for crime they didn’t commit. Two men are free, but the journey isn’t over.

Malcolm Scott and De’Marchoe Carpenter were wrongfully convicted of murder when they were just 18.

Malcolm Scott has changed a lot in his life after spending nearly two decades in prison for a crime he didn't commit.

"I wasn't given this second chance just to get out here and be nothing. You know? God gave me this chance for a reason, and I know this is just the beginning," Scott said.

Strapped to a gurney in Oklahoma's execution chamber, with a fatal cocktail of drugs about to flow into his veins, Michael Lee Wilson declared: 'Malcom Scott and De'marchoe Carpenter are innocent.'
