The kindergarten teacher was separated from her husband at the time of her death. Elizabeth Wall was babysitting the couple's two children at the time she committed the murder.
Wall was a teacher at Kemp Elementary School in Powder Springs.
According to the Paulding County district attorney, Jenna's estranged husband Jerrod Wall, who is an investigator with the district attorney's office, left work to respond to the scene after he was called by police.
Wall and her husband were involved in a contentious divorce with the victim before the shooting and had been separated for over a year.
In a divorce petition, Jerrod Wall alleged his wife was involved in an extra-marital affair with a high school boyfriend. The petition also alleged she revealed that to him after filing for divorce.
