Derrick Harvey, 26, is charged with criminal homicide and being a felon in possession of a weapon during the commission of a felony.
The victim was identified as Tracy Freeman, 51.
On Monday at approximately 7:13 a.m., Chattanooga Police responded to the 1200 block of Peeples Street on a shots fired call.
Officers located the victim deceased from an apparent gunshot wound and secured the scene. Investigators learned that the victim may have been in a verbal altercation with another person prior to the shooting.

Multiple witnesses said "Parlay" was the shooter. "Parlay" was later identified as Harvey.
After a search warrant was issued on Harvey's tent, multiple gunshot shells were found inside. There was also a receipt showing the 12-gauge shells had been bought from Academy Sports.
Surveillance video was obtained showing Harvey buying the 12-gauge shells from Academy. Police said the shells found in the tent are consistent with the ammunition used to kill the victim.
