Memphis musician B.B. Cunningham, 70, a member of Jerry Lee Lewis' band, was shot in Southeast Memphis early Sunday morning, family members confirm.

"I can't believe that that's the way he went out because of … because of some teenager that wanted to rob a store," says his granddaughter Maria Cunningham.

Memphis police say they are investigating the shooting deaths of a 16-year-old male and a 70-year-old male security guard at the complex; MPD says they have not positively identified the victims at this time.

Officers responded to the call at approximately 2:12 a.m. at the Cherrycrest Apartments where they found the bodies in the courtyard of the complex. MPD says both victims suffered apparent gunshot wounds.

"It was devastating at first but the more we think about it, the more reality kind of hits us and it hurts. It hurts a lot," says Maria. "He was a legend. He really was. Memphis lost a really great person."

The preliminary investigation reveals that the security guard heard gunfire coming from the Cherrycrest Apartments. MPS says he responded to the gunfire and was then shot.

Exact details surrounding this incident are unknown at this point. This remains an ongoing investigation.

No arrests have been made at this time.
