Investigators were able to access Leeper’s phone and noticed a recent Cash App transaction involving De’Marcus Currie.

Police claim that after arresting Currie, he admitted to working with two other people to set up Leeper for a meeting in order to steal Leeper’s gun. Leeper tried to fight back during the robbery and was shot as a result.

The St. Louis Circuit Attorney’s Office charged Currie, 18, with first-degree murder, first-degree robbery, and two counts of armed criminal action. Currie remains jailed without bond. He’s due in court on June 11 for a detention hearing.
