Wyatt Testerman, 19, was sentenced to life with parole eligibility after 20 years for the October 2024 murder of his 74-year-old grandmother in Erlanger, Kentucky.

Kentucky Teen Gets Life Sentence for Recorded Murder of Grandmother

A 19-year-old Kentucky man will spend at least the next 20 years behind bars after a judge sentenced him to life in a state correctional facility for beating his grandmother to death — an attack he filmed himself committing.

Kenton County Circuit Judge Patricia M. Summe handed down the sentence Tuesday, ordering Wyatt Testerman to serve life with the possibility of parole after 20 years for the October 2024 killing of 74-year-old Cheri Oliver at her home in Erlanger. Testerman had pleaded guilty but mentally ill in May to a single count of murder.

As Law & Crime has reported, prosecutors described a methodical preparation before the assault. Testerman closed the blinds, rolled up the living room rug and rearranged furniture before knocking his grandmother to the floor. He then punched her more than 40 times, stomped on her approximately a dozen times and repeatedly struck her with a metal drinking tumbler, inflicting the blunt-force head injuries that proved fatal.

Prosecutors further alleged that during the assault, Testerman paused to check Oliver's pulse and said, "How the f— is she still breathing?" before picking up the tumbler and continuing. Prior to the attack, court filings alleged, he had warned that Oliver would "suffer the consequences." His mother told investigators she struck him with a cane in an unsuccessful attempt to intervene.

The case had been on track for trial before Testerman dropped plans to pursue an insanity defense. At his plea hearing, he acknowledged prolonged LSD use and admitted he attacked his grandmother "without reason." His attorney argued at the time that Testerman had been in a drug-induced psychotic state — a claim that fell short of Kentucky's legal standard for insanity because the psychosis stemmed from voluntary drug use.

Defense attorney Timothy Schneider renewed that argument at Tuesday's sentencing, urging Judge Summe to impose the minimum sentence. Schneider told the court that nothing in his client's history indicated he was capable of such violence outside of a drug-induced psychotic episode.

Testerman addressed the court directly, apologizing to his family. "I pray every day that she knows how much I love her and how sorry I am for what I did," he said, according to Cincinnati NBC affiliate WLWT. He also acknowledged, per a report from the Cincinnati Enquirer, that he had initially believed he acted in self-defense before recognizing those beliefs were delusional.

Prosecutors pushed back sharply. Kenton County Commonwealth's Attorney Rob Sanders described it as "the most premeditated murder I've ever seen," the Enquirer reported, citing video footage of Testerman staging the room before the attack and text messages sent beforehand — including one reading, "She will be beaten to a pulp. No mercy for terrorists." Sanders argued the calculated sequence of events undercut any claim to leniency, and after the hearing told WKRC, "The commonwealth is not in the forgiveness business, we are in the justice business."

Judge Summe said she acknowledged Testerman's youth and expressed a belief in the possibility of redemption. But the video evidence left her little room to show leniency. "I don't think it's just about drugs … there was nothing that said that you were on drugs at that point," she said, according to the Enquirer. "If you could do this to your grandmother, I don't know what you could do to the rest of the community."
