Brandon Chapple was 19 when he was killed in Memphis, Tennessee, on December 30, 2009. An African-American and a recent graduate of Fairley High School, his death came during a winter marked by numerous homicides in the city.

The case is cold. The Memphis Police Department’s Cold Case Unit currently has the investigation, and no arrests or publicly identified suspects have been announced. Authorities say investigators continue to seek new leads and encourage anyone with information to contact the unit or CrimeStoppers.

What small detail about that December day might help move this case forward for Brandon’s family?
