Erlanger man who beat his grandmother to death gets life in prison

A man was sentenced to life in prison on Tuesday after pleading guilty to fatally assaulting his grandmother in October 2024.

Wyatt Testerman, 19, was sentenced in Kenton County court after pleading guilty but mentally ill in the death of 74-year-old Cheri Oliver in May. The guilty but mentally ill plea acts similarly to a typical guilty plea, but Testerman will receive psychological care while in prison.

Before Testerman’s sentence, his aunt and mother made victim impact statements, requesting leniency. I simply don’t understand what happened. “I know what Wyatt did was a vicious and brutal act,” his aunt stated. And I just don’t understand why. Why would he harm the guy who was always there for him?

“Testerman addressed his family.” “I pray every day that she understands how much I love her and how sorry I am for what I did,” Testerman added.

Testerman’s defense attorneys urged the judge for a 20-year sentence, claiming that both the state’s and the defense’s expert witnesses agreed that Testerman behaved under the influence of drugs. Testerman acknowledged using LSD for recreational purposes. It takes several months, at least weeks—nearly a month and a half—for his manner to alter, the look in his eyes to change, and him to begin to realize the truth of what happened. ” Testerman’s defense attorney stated.

Kenton County Prosecuting Attorney Rob Sanders, who requested a life sentence for Testerman, stated that there is no medical record or evidence indicating that he had a true, biological mental disease prior to committing the act. Sanders also stated that drug-induced psychosis is not an explanation for Oliver’s death. “The Commonwealth is not in the forgiveness business,” Sanders declared. “We’re in the justice business.” Sanders continued, “We can’t trust (Testerman) not to do more drugs.”

Testerman was arrested after police responded to an allegation of an attack at a home in the 100 block of Ridgewood Drive around 2 p.m. on October 8, 2024. When they arrived, they discovered Testerman outside and Oliver inside the property. “There is never a rhyme or reason to this,” Sanders told reporters following the sentencing. “There is no explanation at all. This mom did nothing to provoke her grandchild. Certainly nothing comes close to justifying the violence that was committed against her.”

In court in 2024, Detective Tom Loos of the Erlanger Police Department stated that Oliver was discovered lying in a pool of blood and was transferred to UC Medical Center, where she was pronounced dead.

Loos stated that Testerman began punching Oliver with his hands and a metal cup following an incident and quarrel involving Testerman, his grandparents, and his mother.

In October 2024, Testerman yelled at the judge, “Innocent until proven guilty.” Can it be established that I believed she didn’t have a weapon? Testerman questioned the judge, who did not react to his inquiries.

Testerman’s defense team sought a release from jail to attend his grandmother’s burial, but the judge denied the request. Absolutely not. Sanders responded to the defense’s request for a burial by saying, “She wouldn’t need one if he hadn’t killed her.” “That’s the most ridiculous request.”
