Anthony Martin, 36, known to friends as Chris, was killed on the evening of August 18, 2024, after a dispute over a residential parking spot at a memorial cookout in the 1300 block of N. Spring Street in East Baltimore. The gathering, tied to the Thunderguard Motorcycle Club, erupted into gunfire around 8:01 p.m.; investigators later concluded there were multiple shooters and ballistic evidence indicated at least ten different firearms were used. Martin was struck by multiple gunshots and died at a local hospital. Seven other people — a woman and six men aged 22 to 46 — were wounded and survived.

Baltimore Police used surveillance footage to identify a suspect and on October 7, 2024 arrested 43-year-old Eric Kibler, a member of the motorcycle club, charging him with first-degree murder and numerous related offenses. At trial in March 2026 a jury acquitted Kibler of the murder and other serious charges but convicted him of two handgun offenses: illegal possession of a regulated firearm and carrying a handgun without a permit. The jury was deadlocked on several counts, including conspiracy to commit first-degree murder, and the prosecutor announced plans to seek a retrial on unresolved charges. As of March 2026 Kibler was awaiting sentencing on the handgun convictions and a possible second trial.
