Atlanta police have arrested a 51-year-old man in the brazen daylight killing of a man in his vehicle last fall, according to a news release. Denorris Turner was arrested Monday and charged with Felony Murder, Aggravated Assault and Criminal Attempt in the killing of Graham Sisk, 23.

The Atlanta Police Department said Turner was transported to the DeKalb County Jail, where he was being held Monday night. Turner is the second man to be arrested in the crime. In November, police arrested Shaheed K. Huff, 30, in Lithonia and charged him with felony murder and aggravated assault with a weapon.

Sisk was killed Oct. 5 in the afternoon shooting at the busy intersection, shocking many in the Virginia-Highland/Druid Hills community. According to APD, Sisk was traveling northbound on Moreland Ave approaching Ponce De Leon when "suspects approached him and fired multiple times. ...It appears that there may be two suspect vehicles and multiple suspects involved."

Monday's release about Turner's arrest said that witnesses told police that before the shooting, there had been "an altercation" that began "on Moreland Ave. with the victim and the occupant or occupants of an older model Ford or Chevrolet pick- up truck that was described as either dark blue or black."

In November, Paul Guerrucci, the homicide commander for APD, said the investigation found that the shooting was not a random act of violence:

"All indications are that all the individuals that were involved in this shooting and killing ... knew each other in one way or another, and they were involved in some type of illegal activity when this shooting occurred." See also:
