Gavonte Lampkin was 20 when he was killed in New Orleans in the summer of 2018. On July 29, Lampkin and 18-year-old Shantrell Parker were found shot and burned in a wooded area of the Algiers neighborhood.

Police identified two suspects, Michael Tyron Robinson, then 24, and Kirk Powell, then 23, and charged both with second-degree murder. A witness said Powell and Robinson killed the pair at a residence on Tullis Drive in Algiers and later moved the bodies. Prosecutors tied Lampkin’s killing to his role as a witness in a separate case; Lampkin had survived two prior shootings and was scheduled to testify against Christopher Butler, and authorities said a second attack on him was meant to stop that testimony.

What information about Lampkin’s last days or the Algiers crime scene might help fill remaining gaps in this case?
