Richard Glossip, who has been on death row in Oklahoma for more than two decades, is set to be executed on May 18th. Glossip was found guilty of arranging the murder of his employer, Barry Van Treese, in 1997. However, two independent investigations have cast serious doubts on his conviction: the first found, “No reasonable juror hearing the complete record would have convicted Richard Glossip of first-degree murder,” while the second concluded that Glossip’s conviction should be vacated and a new trial granted. Despite this, the Oklahoma Court of Criminal Appeals has ruled 5-0 to deny a request for another appeal. A group of high-profile supporters, including Sister Helen Prejean and Susan Sarandon, have mobilized to try to spare Glossip’s life, and have part-funded both independent investigations into the case. Public opinion in Oklahoma is divided: while the prosecution argues that there is “overwhelming evidence” against Glossip, and the victim’s family have demanded his execution be carried out, the case has been mired in accusations of witness intimidation and poor police work. In the words of one commentator, “a man’s life hangs in the balance[,] and it is not at all clear that he is guilty.”
