Jermaine Mitchell was 23 when he was shot and killed in Baltimore on the evening of May 26, 2017 after an argument among family members escalated. Emergency services responded but Mitchell died of his injuries.

Baltimore police identified a family member as a focus of the investigation, and within days they arrested David Warren, Mitchell’s brother-in-law. Warren was charged with murder in connection with the shooting.

What details about that night or the family dynamics might help explain how a domestic argument turned deadly, and can anyone who knew Jermaine or the family provide information to investigators?
