Keyon Sonnier was 29 when he was shot and killed on December 15, 2015, in Marrero. The shooting was a double attack that left another person wounded; that surviving victim received medical treatment but has not been widely identified in reports. The Jefferson Parish Sheriff’s Office opened an investigation into the incident, though initial details about what led to the shooting were scarce.

Years after the killing, a man named Carlos Heard was charged with Sonnier’s murder. News accounts have not set out the investigative steps that produced the charge, nor have they publicly detailed a motive or the current status of the legal case. Sonnier’s family was left grieving after his death; many questions about the circumstances remain unanswered.

If anyone knew Keyon, was in Marrero on December 15, 2015, or has information about the shooting, please share what can help the investigation.
