Christopher Collins, sentenced to death for the 2007 rape and murder of 9-year-old Rowan Ford, is set to be executed in Missouri. This will mark the state’s fourth execution this year and the 23rd in the U.S. since January. Collins was convicted in 2012 after abducting, raping, and strangling Ford, whose body was found a week later. All legal avenues for appeal have been exhausted, with both the U.S. Supreme Court and Missouri’s Republican Governor Mike Parson denying requests for a stay of execution.
