A family barbecue in Milwaukee turned deadly on September 7, 2019, when 24-year-old tattoo artist Demetrius Holmes was shot and later died from multiple gunshot wounds.

Family members said the shooting began after Dominique Chambers, 24, who lived across the street, drove past the gathering, circled the block twice, parked in a nearby alley and then walked up to the residence armed with a handgun. Witnesses reported Chambers looked at Holmes, warned him not to move, then opened fire. Police recovered numerous shell casings at the scene, including 13 9mm casings in the street and seven .40 caliber casings across the street. Family members identified Chambers, known as D-Boy, as the shooter and said there may have been two other shooters.

An arrest warrant was issued for Dominique Chambers, and he was charged with one count of first-degree recklessly endangering safety, as party to a crime, use of a dangerous weapon. Did anyone at the barbecue or nearby that night see vehicles, people, or actions that could help clarify what happened?
