MARIETTA, Ga - A woman accused of killing her daughter-in-law while her grandchildren were waiting outside in her car pled guilty but mentally ill Friday afternoon.

According to the Cobb County district attorney, Elizabeth "Betsy" Wall shot and killed Jenna Wall, 35, on June 23, 2016. At the time of the murder, Jenna Wall was separated from her husband, Jerrod, and they shared custody of their two young sons.

Instead of taking them swimming, Elizabeth Wall drove to the residence where Jenna Wall was staying with her parents.

"The boys played upstairs while the two women talked, and then Elizabeth Wall took the boys back out to her vehicle," said Cobb DA Vic Reynolds. "She called her son, told him to come get the boys from Jenna’s house, and disconnected the phone. She then left the two boys in the vehicle with the phone, went back inside Jenna Wall’s house, and shot the young mother four times with a .357 revolver."

When Jerrod Wall arrived at the home, he found his mother holding the gun to her head, with Jenna Wall was dead on the kitchen floor.

Chief ADA Jesse Evans told the court that forensic searches of the defendant’s phone found disparaging text messages about the victim as well as web searches regarding mental disorders, murder suicides, and wrongful-death liability.

“Those clearly showed that some thought went into this crime,” Evans said.

After accepting the plea, Cobb Superior Court Judge Reuben Green sentenced Elizabeth Wall, now 64, to life in prison. Watch the sentencing below.
