Queens District Attorney Melinda Katz is again asking the public to help break open the 2020 killing of off-duty correction officer John Jeff, renewing a plea on June 27, 2026, for anyone with information to come forward. The homicide, which unfolded in Jamaica, Queens, has remained unsolved for six years, and prosecutors say fresh tips could finally move the case. Katz’s latest appeal continues a long-running effort by the DA’s Cold Case Unit to pore over old evidence and surveillance footage in hopes of finding something investigators might have missed the first time around.
In a post on X, Katz urged people to DM @NYPDTips or call 1-800-577-TIPS and wrote, “It is never too late for justice.” She also used the hashtag #ColdCaseUnit to spotlight her office’s ongoing push to revisit unsolved killings across Queens.
