Execution of Delaware Killer Delayed: The Associated Press reports U.S. Chief District Judge Gregory Sleet on Wednesday halted the Delaware execution of Shannon Johnson, saying he needed more time and information before deciding whether the state court was right in concluding that Johnson was mentally competent. Johnson was sentenced to death for the 2006 shooting death of a 25-year-old man after Johnson found him sitting in a car with his ex-girlfriend. Johnson also later shot his former girlfriend, but she survived. Prosecutors immediately began preparing an appeal of Sleet's ruling. Johnson was scheduled to be executed Friday. He has waived his right to future appeals.
