On the morning of September 8, 2017, work on a flood-damaged house on Thomas H. Delpit Drive in Baton Rouge ended in violence. Donovan Troy Cummings, 49, and Harold Anthony were renovating the property when a gray or silver newer-model Mazda CX-9 pulled up at about 9:45 a.m., two or three men exited, chased the two men and opened fire. Harold Anthony was pronounced dead at the scene; Donovan Cummings was taken to a hospital and died later that day.

Investigators linked Harold Anthony to a large-scale drug trafficking operation, a connection that investigators say may explain the daylight attack. Hours after the shootings, David Walker — who had been questioned by police and lived on the same street — was found shot to death in his vehicle; investigators believe he may have been silenced as a witness. Several people have since been arrested on related charges, and authorities say Martrell Harris, Dexter Collins and others are tied to the broader criminal enterprise and to Walker’s killing, but no one has been charged directly with the murders of Donovan Cummings and Harold Anthony. The East Baton Rouge District Attorney’s Office says the homicides remain under active investigation.

Does anyone have information about activity near Thomas H. Delpit Drive on September 8, 2017 or about the Mazda CX-9 seen that morning?
