The State Bureau of Investigation is now looking into what happened along with detectives from the Major Crimes Division of the Fayetteville Police Department.
Officer Yount has been placed on administrative duty, which is routine after an officer involved shooting.
Davis' family is questioning what happened. They say he was shot three times in the back, and that evidence in the case may have been tampered with.
"Justice will be done. The officer who shot him shot the wrong one, and we are not going to let it go," said Davis' aunt Daisy Davis.
A neighbor who lived near the place where the shooting happened claimed Officer Yount picked up shell casings.
This is the second shooting involving Yount this year. In June, he shot one of three burglary suspects in the leg when the men jumped him. He was cleared of any wrongdoing in that incident.
Officer Yount has been with the Fayetteville Police Department since January 2002.
