Mother-in-law pleads guilty in murder of Cobb County teacher

COBB COUNTY, Ga. - The family of a murdered Cobb County teacher found a sense of closures just days before the case was to go to trial.

It's been almost two years since Jenna Wall was shot and killed at the hands of her mother-in-law, Elizabeth Wall. Standing with her attorney at her side, the 64-year-old woman entered a guilty but mentally ill plea Friday. In the courtroom filled with Wall's family and friends, Cobb County Superior Court Judge Reuben Green sentenced Elizabeth Wall to life in prison.

Wall admitted shooting and killing her daughter-in-law in June 2016.

Defense attorney Jim Berry told FOX 5 News Wall had fairly obvious mental problems which he said led to the shooting. He said Wall heard voices and believes she would have ultimately shot herself.

Jenna Wall was a teacher at Kemp Elementary School. According to authorities, she was home with her boys when her mother-in-law came over that fateful morning. Investigators said Elizabeth Wall called her son at work and told him to come and get the boys and then investigators said she took the boys to her truck parked outside, went back inside, and shot her daughter-in-law in the kitchen.

When Wall’s son arrived on the scene, he found his wife dead and his mother holding the gun to her head. Jenna Wall was as shot four times with wounds to her head, chest, torso, and abdomen.

At the time of the shooting, Jenna and her husband were going through a divorce and working out custody arrangements.
