-- A Missouri man convicted of ambushing and killing a St. Louis area police officer he blamed in the death of his younger brother was executed Tuesday night.Johnson saw officers arrive and awoke his 12-year-old brother, Joseph “Bam Bam” Long, who ran to a house next door.That evening, McEntee returned to the neighborhood to check on unrelated reports of fireworks being shot off.The court filing said Johnson walked down the street and told his mother that McEntee “let my brother die” and “needs to see what it feels like to die.” Though she told him, “That’s not true,” Johnson returned to the shooting scene and found McEntee alive, on his knees near the patrol car.Johnson’s 19-year-old daughter, Khorry Ramey, had sought to witness the execution, but a state law prohibits anyone under 21 from observing the process."
