Dion T. Sanders, of St. Louis, was sentenced to 16 years in prison in a plea deal over a deadly 2016 holdup.

Sanders pleaded guilty Aug. 24 to reduced charges of second-degree murder (also called felony murder), assault, attempted robbery and three counts of armed criminal action.

Sanders was charged in February 2017 with first-degree murder and the other counts in the Dec. 22, 2016, shooting death of Keith Armstrong and the wounding of another man.

Sanders approached Armstrong, 56, and another man, then 65, who were on a front porch shortly before 10 p.m. in the 2000 block of Destrehan Street in the city's Hyde Park neighborhood, charges said. Sanders announced a holdup, and after a struggle, shot Armstrong in the chest and the other man in the hand.

Armstrong ran, and the other man retreated into the house and was shot at least twice more in the arm and leg, police say. Armstrong was found by police dogs about an hour later in a rear yard in the 2000 block of Agnes Street, which runs parallel to Destrehan and is a block to the south.
