Richard Eugene Glossip is an American prisoner currently on death row at Oklahoma State Penitentiary after being convicted of commissioning the 1997 murder of Barry Van Treese. The man who murdered Van Treese, Justin Sneed, had a "meth habit" and agreed to plead guilty in exchange for testifying against Glossip. Sneed received a life sentence without parole. Glossip's case has attracted international attention due to the unusual nature of his conviction, namely that there was little or no corroborating evidence, with the first case against him described as "extremely weak" by the Oklahoma Court of Criminal Appeals.
