Leonard Arnold was 32 when he was shot dead in Saint Louis, Missouri, on December 2, 2015. Few details about the initial circumstances were released at the time, leaving questions about where he was or what led to the shooting.

Investigators continued working the case into the following months. In early 2016 a 50-year-old man was arrested and later charged with first-degree murder and armed criminal action; charging documents allege he shot Arnold. No public information about a motive or the relationship between Arnold and the accused has been provided, and the case was preparing to proceed through the courts.

If anyone knew Leonard Arnold, his movements that day, or has information about the events around December 2, 2015, please come forward to help clarify what happened.
