On the night of June 17, 2017, 22-year-old Demarco Mars was fatally shot in the Vanderlou neighborhood of St. Louis, Missouri. Police were called about 10:00 p.m. to the 3800 block of Labadie Avenue, where they found Mars with fatal gunshot wounds; he was pronounced dead at the scene. The shooting was one of several violent incidents that weekend in the city.

Investigators say Mars had been walking with another man when a dark-colored vehicle pulled up and occupants opened fire. The companion was not injured and told police what he saw, but there was little chance to identify the attackers during the sudden drive-by attack. The St. Louis Metropolitan Police Department opened an investigation and initially reported no suspects in custody; no arrests or charges have been publicly reported.

If anyone saw the vehicle or has information about that stretch of Labadie Avenue on the night of June 17, 2017, contact investigators with tips.
