BARTOW COUNTY, Ga. – The tragic murder of Heather Dianne McDonald, a 27-year-old mother of three from Cartersville has ended in a guilty plea and a life sentence for Richard Dale Harden, the man responsible for her death. This case has gripped the local community for nearly eight years.
Heather McDonald was last seen on September 18, 2016, in Cartersville. She was wearing yoga pants and a tank top when she vanished from the vicinity of U.S. Highway 411 and Interstate 75.
Her red Jeep Wrangler was found abandoned at the Courtesy Inn parking lot with her belongings inside and the key on the ground. The car’s open door and missing person set off an urgent search by family, friends, and local authorities.
The FBI and Georgia Bureau of Investigation joined the search efforts, offering a reward of up to $20,000 for information leading to her recovery or the identification of those involved in her disappearance. Despite the extensive search, it took several weeks before McDonald’s body was discovered.
On October 30, 2016, hunters in Haralson County, approximately 50 miles from her home, found her remains in the woods. At the time of discovery, the cause of death was not immediately known, and additional tests were needed to determine the precise manner of her death.
Richard Harden, a 64-year-old Cartersville resident with a troubling criminal history, emerged as a person of interest in the case. Harden had a background of sex offenses dating back to the 1980s, including child molestation and enticing a child.
Although McDonald’s family had not seen him for years, he was known to them and had been seen around McDonald’s residence.
On October 7, 2016, U.S. Marshals and Cartersville police attempted to arrest Harden on unrelated charges in Carroll County. During the arrest, Harden barricaded himself and made statements implying knowledge of McDonald’s disappearance, including the admission that he was aware of “that missing girl.” His suspicious behavior and the forensic evidence gathered during this time intensified the investigation into his involvement.
Investigators found Harden’s DNA under McDonald’s left-hand fingernails and a female sock in his truck. Harden’s cell phone geolocation data tracked his movements from Cartersville to Haralson County around the time of McDonald’s disappearance. Text message records revealed frequent communication between Harden and McDonald that ceased abruptly on the day she went missing.
In a post-Miranda interview, Harden confessed to having a sexual relationship with McDonald in exchange for drugs. He admitted to strangling McDonald and disposing of her body in Haralson County. This confession, coupled with the forensic evidence and geolocation data, solidified Harden’s role in the crime.
On August 6, 2024, Richard Harden pleaded guilty to felony murder in the Superior Court of Bartow County. He was sentenced to life in prison without the possibility of parole. The plea agreement was reached after consideration of the impact on McDonald’s family and the desire to avoid the trauma of a trial.
During the sentencing, Heather McDonald’s parents spoke about the profound impact of Harden’s actions on their lives. District Attorney Erle J. Newton III, who prosecuted the case, expressed hope that the conviction would provide some measure of peace and justice for McDonald’s family. “We can never restore full peace to them; we can’t bring Heather back, but at least we came to a just result,” Newton said.
Multiple agencies investigated the case, including the Cartersville Police Department, the Bartow County Sheriff’s Office, the Georgia Bureau of Investigation, the United States Marshal Service, the Federal Bureau of Investigation, and local sheriff’s offices from Haralson and Carroll counties.
