Lance Shockley was condemned for killing Missouri State Highway Patrol Sgt. Carl Dewayne Graham Jr. in March 2005. Prosecutors say Shockley waited for hours near the trooper's Van Buren home in southeast Missouri before shooting him with a rifle and shotgun after Graham exited his patrol vehicle.

Shockley, 48, is scheduled to receive a lethal injection after 6 p.m. local time at the state prison in Bonne Terre, Missouri.

His is one of two executions scheduled for Tuesday evening in the U.S. In Florida, Samuel Lee Smithers , 72, is set to receive a lethal injection for killing two women whose bodies were found in a rural pond in 1996.
