The chief medical examiner in Saint Louis has ruled the death this summer of a Warren G. Murray Developmental Center employee a homicide.  Dr. Michael A. Graham signed the ruling Friday, declaring the death of 56-year old Rick Stewart of Shattuc, a homicide.  Stewart was working Third Shift at the Centralia facility on July 30^th, when a resident of Apple cottage reportedly punched him in the chest and Stewart fell to the floor.  He reportedly got up, returned to work and later suffered a heart attack while still on shift at Murray.  Stewart was transported by ambulance to Saint Mary’s Good Samaritan Hospital in Centralia, but was ultimately moved to Barnes-Jewish Hospital in Saint Louis, where he was reportedly kept on life support until August 6^th.  Just days after Stewart’s death, the resident who allegedly punched him in the chest was transported to the Clyde L. Choate Developmental Center in Anna, a transfer that reportedly was already in the works at the time of the July 30^th incident.  Attorneys representing Stewart’s widow declined to comment on the homicide ruling until they had time to review the medical examiner’s report.  This is the second homicide ruling in less than a month to come out of the Murray Center.  On November 12^th, a Marion County Coroner’s Inquest jury ruled the March death of resident Todd Clementz was a homicide.  That case has been handed over to the Clinton County State’s Attorney for possible prosecution.
