David Walker Jr., 68, was found dead inside his Chevrolet Impala on the evening of September 8, 2017, in the 3600 block of Seneca Street in Baton Rouge. He had suffered apparent gunshot wounds and was pronounced dead at the scene.

Investigators linked Walker’s killing to a double homicide earlier that day, when his friend Harold Anthony and Donovan Cummings were shot while renovating a home. Rumors circulated that Walker had witnessed those morning slayings. Hours later Walker reportedly received a call from a prepaid cellphone and was lured to the Seneca Street location where he was killed.

Authorities traced that prepaid phone to Terrell Anthony, Harold’s brother. A confidential informant told police that Terrell Anthony and associates lured Walker and carried out the killing. Terrell Anthony was arrested in October 2018 and charged with second-degree murder; he was released on a $300,000 bond in fall 2019 with house arrest and GPS monitoring. Another man, Dexter Collins, was arrested in February 2020 on a first-degree murder charge in the case, but those charges were later dropped for lack of evidence; Collins remained in custody on unrelated allegations.

Did anyone know Walker’s movements or who called him that evening?
