The deceased man was identified as Daniel Robbins, while the victim was identified as Jessica Folds, 47.
According to media reports, Robbins allegedly tried to dispose of Folds' body in a wooded area near Lanett, Alabama.
Authorities later found the bodies of both Robbins and Folds lying next to each other in brush beside a roadway.
An autopsy determined that Folds died from strangulation, Upper Michigan Source reported.
Robbins is believed to have suffered a fatal heart attack. His ex-wife told the news outlet that he had a pre-existing heart condition.
Folds lived just a few kilometres from the location where her body was discovered.
According to her obituary, she is survived by three sons and two grandchildren.
"Jessica lived and worked in many places throughout the Auburn-Opelika area. Jessica touched the lives of many with her heart of gold, deep love for everyone, and smile that brightened the world," the obituary said.
