Missouri Gov. Eric Greitens halted inmate Marcellus Williams' execution Tuesday after DNA evidence raised questions about his guilt.
The Republican governor said he was issuing a stay for Williams, who was convicted of fatally stabbing former St. Louis Post-Dispatch reporter Lisha Gayle during a burglary at her home in 1998. Williams was scheduled for execution at 6 p.m. on Tuesday.
The decision comes after Williams' attorney pointed to DNA evidence found on the murder weapon that matched another unknown person. St. Louis County prosecutor Bob McCulloch, however, argued that there was plenty of other evidence to convict Williams.
Missourians for Alternatives to the Death Penalty (MADP) as well as the state's NAACP chapter delivered copies of more than 185,000 signatures asking Greitens to save Marcellus Williams.
Greitens said he plans to appoint a five-member board to recommend whether Williams should be executed. So far, no timetable has been set.
