Frederick Gett

Frederick Jett, 45, was shot and killed on Aug. 28 during a robbery near Glen Owen Drive and Bahama Court in Ferguson. Authorities this week charged Jerry Watkins with first-degree murder, two counts of first-degree robbery and two counts of armed criminal action. He was in custody Friday on a $1 million cash bond. A 17-year-old boy, who has not been identified because he is a minor, was charged with second-degree murder, first-degree robbery and armed criminal action. Authorities say the two shot and killed Jett while trying to rob someone else. Police found Jett after getting an alert from ShotSpotter, a system that uses microphones to detect the location of gunfire. Jett lived in the 1000 block of Geringer Court, about three miles from where officers found him. Court documents say Watkins and the teenager robbed a person at gunpoint and stole cash from the man as he was leaving his residence. The next day, police say Watkins and the teenager approached another person who was with Jett. They showed the two a handgun and demanded cash and other items, police said. They stole a purse, phone and other items from the person Jett was with, and then shot Jett when they tried to steal from him.
