ST. LOUIS, MO. (KMOX) — The Missouri high court has upheld a man’s conviction and death sentence in the ambush killing of a state trooper.
Lance Shockley of the southeast Missouri town of Van Buren was convicted of first-degree murder for the killing of State Highway Patrol Sgt. Carl Dewayne Graham Jr. on March 20, 2005.
Graham was shot in the back of the head as he returned home from work.
Shockley was a suspect in an fatal traffic accident investigation led by Graham.
Shockley was arrested in Graham’s murder three days later. He has been on death row since 2009.
In his appeal, Shockley alleged that errors were made while preparing the trial transcripts, along with evidentiary and instructional errors. He also alleged a juror tainted deliberations and the sentence was disproportionate to the evidence.
The Missouri Supreme Court disagreed in an unanimous ruling.
