Cobb District Attorney's Office solves homicide from 1972
(Marietta, GA – Sept. 18, 2023) For more than 50 years, the mystery of who killed a young Marietta girl has haunted investigators and troubled the community. Nine-year-old Debbie Lynn Randall was reported missing on Jan. 13, 1972, when she failed to come home from the nearby laundromat.
The Office of District Attorney Flynn D. Broady, Jr. confirms the killer is William B. Rose of Mableton.
According to detectives, the third grader from Pine Forest Elementary School was walking home from the laundromat when she was abducted, raped and strangled to death. The laundromat was only a half block away and the only clue was spilled detergent across the street from her home. A near-citywide search was organized by various community groups including the Concerned Citizens Committee, a group of ham radio operators and Cobb and Marietta Civil Defense workers. “Operation Debbie” garnered 4,000 volunteers to search for the missing girl.
Her body was found on Jan. 29, 1972, by a group of Southern Tech students about 1,000 feet south of Windy Hill and Powers Ferry Road. Marietta Police detectives investigated and followed up on hundreds of leads without success.
The Cobb County Cold Case Unit received the case in 2015. Evidence recovered from the scene was sent for updated DNA analysis and searched in the Combined DNA Indexing System (CODIS) without results. In the years that followed, with the advancement of genetic genealogy technology, additional efforts were made to review evidence and a SNP profile was developed. After many years, a familial descendant's DNA profile was found. The suspect’s body was exhumed, and DNA tests confirmed Williams B. Rose was responsible for the death of Debbie Lynn Randall. He was 24 at the time of the crime and committed suicide in 1974. Investigators confirmed that Rose had acquaintances who lived in the same complex as the victim.
“The loss of a loved one, especially one of such a tender age is difficult to comprehend. This family has waited for decades for an answer. This information will not replace the pain of losing Debbie Lynn. We are very grateful for the unwavering dedication, persistence and commitment from Det. Ron Alter of the Cold Case Unit and all our partner agencies to provide some closure to this case,” said Cobb District Attorney Flynn D. Broady, Jr. “The mission of our office is to deliver justice regardless of how much time has passed. In this case, the suspect took his own life two years after the death of the Debbie Lynn Randall.”
Both of Debbie Lynn’s parents died without an answer to her death. Her mother Juanita died of leukemia in 2018 and her father, John, passed away in January 2022.
