Mosley was pronounced dead at his home in the 9000 block of Neely Lane after Knox County deputies responded to a reported shooting just before 2 a.m. on Jan. 31.

According to court documents, Harper, who lives next door, told his brother that he was upset with Mosley and was going to kill him.

After the statement, investigators said Harper went to Mosley’s home and shot him twice with a rifle and fled the scene, according to court documents.

Court documents state that Harper called his father after the shooting and his father then assisted officers in locating him.
