A summer pool party at Glen Burnie Park Swim Club in Anne Arundel County on July 5, 2019, ended in deadly violence. About 300 people were attending when shots rang out around 11:15 p.m. Responding officers found 29-year-old James Antonio Diggs IV of Gwynn Oak suffering multiple gunshot wounds; he was taken to the University of Maryland Shock Trauma Hospital and later died. Two other partygoers, a 21-year-old woman and a 27-year-old man, suffered non-life-threatening injuries.

Witnesses described an altercation that began when a Nissan Altima driven by 21-year-old Jacovi Devaughn Johnson struck Diggs. Testimony says Diggs jumped on the car and broke the windshield; Johnson then allegedly retrieved a handgun from the glove compartment, exited the vehicle, and fired. An autopsy reported multiple gunshot wounds, including rapidly fatal wounds to the back of the head and mid-back.

Johnson was arrested July 8, 2019, in Ocean City and charged with murder, assault, and firearm offenses. A second man, 20-year-old Dion Isom Sanders, was arrested on handgun charges after a witness said he hid a firearm near the scene. Did anyone at the party see what led up to the confrontation or the moments after the shooting?
