Prosecutors raise concerns about lack of evidence as family of victim supports saving Williams from the death penalty

Missouri is slated to execute a man on death row on Tuesday, despite objections from prosecutors who have suggested he was wrongfully convicted.

Marcellus “Khaliifah” Williams, 55, is due to be killed by lethal injection even after the office of the St Louis county prosecuting attorney, which originally convicted him, sought to have his case overturned. Prosecutors have raised concerns about the lack of DNA evidence linking Williams to the 1998 killing of Lisha Gayle and have said that Williams did not get a fair trial.
