On the evening of December 23, 2011, 24-year-old Lawrence A. Jones Jr. was shot and killed during a traffic stop in Pittsburgh’s Knoxville neighborhood involving two undercover officers, Jeffrey John Abraham and Joseph P. Fabus. According to the officers, they saw a gun after pulling over the vehicle Jones was driving and say he was shot as he attempted to flee. Jones’s family disputed that account, insisting he was unarmed and heading out for last-minute Christmas shopping; his father said Jones would not have posed a threat.

Marie C. Reese, Jones’s mother, filed a federal lawsuit in November 2012 alleging excessive force and inadequate training for undercover officers.

Did anyone in Knoxville that night see Jones’s vehicle or have information about what happened during that traffic stop?
