CANTON — A 19-year-old woman was shot and killed Sunday morning near the doorway of a family member’s home in Cherokee County.

The victim’s boyfriend, whose criminal history includes 10 arrests in Cobb County since 2008, is accused of the killing.

Already on probation in Cobb at the time of his arrest according to Cobb Superior Court records, Trevor Nuckles, 21, has been charged with the murder of his girlfriend, Dejanirra Elrod, who was shot several times just after midnight Sunday, investigators said.

An autopsy report completed on Monday showed that the victim was struck three times, according to Maj. Ron Hunton, head of criminal investigations for the Cherokee County Sheriff’s Office.

Hunton said the investigation showed that a total of six shots were fired at the victim.

Elrod, who was known as “DJ,” died after being taken to WellStar Kennestone Hospital in Marietta.

Investigators are continuing to examine the relationship between the victim and the suspect, Hunton said.

Residents who know the family said the victim was trying to end her relationship with Nuckles.

“We’ve heard it was an on-again, off-again relationship, and we are still looking at history between them,’ Hunton said. “We are still in process of pulling all police reports relating to Nuckles.”

Lt. Jay Baker, spokesman for the Cherokee County Sheriff’s Office, said no one saw the shooting, but the relative who owned the home told investigators Nuckles had just left.

“When the homeowner tried to call 911, Nuckles grabbed her phone and threw it to the ground before leaving the scene on foot,” Baker said.

A Canton police officer arrested Nuckles less than two miles away, walking near the River Ridge apartment complex where he lived with Elrod, Baker said.

“With the assistance of the Cobb County Sheriff’s Office K-9 Team, investigators searched the woods between the crime scene and where Nuckles was apprehended,” Baker said. “A 9mm handgun, believed to be the murder weapon, was located approximately 50 yards from the crime scene in the woods off Pine Grove Road.”

In addition to the murder charge, Nuckles has been charged with possession of a firearm by a convicted felon, possession of a firearm during the commission of a felony and obstruction of a 911 call, Baker said.

He is being held without bond at the Cherokee Adult Detention Center.

On Christmas Day, Nuckles was arrested in Cobb after he allegedly punched a relative twice in the right side of the man’s face during an argument with Nuckles’ mother, according to an arrest warrant.

Nuckles was also arrested in June 2010 on a felony drug charge and misdemeanor charges of obstruction and giving a false name, according to an arrest warrant.

Five months later, Nuckles was also charged with felony aggravated battery in November 2010. According to an arrest warrant, Nuckles allegedly kicked a man twice in the head and then stood on him, leaving him unconscious and bleeding.

The incident reportedly began when the victim yelled at Nuckles, who was allegedly kicking a car.

In April 2011, Nuckles pleaded guilty to battery and was sentenced to time served in prison and three years’ probation, according to information from the Cobb County Superior Court clerk’s office.

Elrod is survived by a son, her parents, a brother and several family members, according to her obituary.
