Memphis police say 70-year-old B.B. Cunningham died Sunday. He was working as a security guard at an apartment complex when he was shot.
Police said a 16-year-old boy and a 22-year-old man had fired shots at another security guard when Cunningham responded.
Cunningham chased them into another apartment complex. When the second guard arrived, he found Cunningham and the 16-year-old fatally shot in a courtyard.
Police spokeswoman Karen Rudolph says the 22-year-old man, who had fled the scene, has been charged with first-degree murder for allegedly shooting Cunningham.
Cunningham had a 1967 hit, "Let it All Hang Out," with his own band the Hombres.
