Sidney D. Smith was 18 when he was found dead inside a residence in the Shawnee neighborhood of Louisville on Sunday, July 23, 2017. Officers responded shortly before 5 p.m. to the 3600 block of Vermont Avenue near Young Elementary School and discovered Smith had sustained a gunshot wound; the coroner listed a gunshot wound as the cause of death and he was pronounced dead at the scene.

Neighbors told news crews they had not heard any gunshots, a detail that contrasts with the official cause of death. Family and friends remembered Smith as a great kid; funeral services were held at Antioch Missionary Baptist Church. The Louisville Metro Police Department investigated, but the case grew cold. No arrests have been announced and police have not publicly identified any suspects.

What details about that afternoon or about Sidney’s movements before he was found might help bring new information forward? If anyone knew him or saw something on Vermont Avenue that day, please come forward with tips.
